PostgreSQL 9.3 extension treats for windows users: plV8

nospam@example.com (Leo Hsu and Regina Obe) — Mon, 13 May 2013 15:09:00 -0400

Now that PostgreSQL 9.3 beta1 has been released we've started to jump start our experimentation by compiling our favorite extensions. First on the list is PL/V8 js.

This was compiled against 9.3beta1 for 64-bit and 32-bit and plv8 version 1.4.0. We briefly tried with the EDB windows builds which we downloaded from: http://www.enterprisedb.com/products-services-training/pgbindownload and seems to work fine.

We hope windows users find these useful.

pgRouting windows binaries for PostgreSQL 9.2 32-bit and 64-bit

nospam@example.com (Leo Hsu and Regina Obe) — Tue, 09 Apr 2013 00:26:00 -0400

We've got experimental pgRouting windows binaries available for windows PostgreSQL 9.2 32-bit and 64-bit for pgRouting 1.0.7 development branch. More details on our Boston GIS blog page.

The final versions we plan to release with upcoming PostGIS 2.1 PostgreSQL 9.2 on stackbuilder as part of the PostGIS install. Barring no difficulties we'll also have experimental binaries for PostgreSQL 9.3 releases once 9.3 reaches beta.

This version and upcoming pgRouting versions support the PostgreSQL extension model, so if you have postgis already installed, its just an additonal simple step:

CREATE EXTENSION pgrouting;

PostgreSQL 9.2 windows binaries for file_textarray_fdw

nospam@example.com (Leo Hsu and Regina Obe) — Sat, 19 Jan 2013 14:06:00 -0500

We discussed a while back the Text array foreign data wrapper that allows you to register and query a delimited file as if it were a regular table with one array column. It's probably the FDW we use most often and reminded of that recently when I had to query a 500,000 record resident list tab delimited file to prep for geocoding.

When we upgraded to 9.2 and we could no longer compile, I wrote to Andrew Dunstan about this and he kindly created a 9.2 version. Unfortunately there are still quite a few FDWs broken as a result of the 9.2 changes and I was hoping to try to apply similar patches to them that I saw Andrew do, but haven't had the patience or time yet. Anyway we've compiled these for 9.2 under our mingw64-w64 and mingw64-w32 chains using Andrew's 9.2 GitHub stable branch. https://github.com/adunstan/file_text_array_fdw/tree/REL9_2_STABLE and we've tested them using the PostgreSQL EDB windows VC++ compiled versions. We hope you find them as useful as we have.

I'm hoping to add more FDWs to these 9.2 bags once we have those working again. If you want to compile yourself or compile others, we have instructions in the packaged README.txt.

PLV8 1.3 windows binaries for PostgreSQL 9.2

nospam@example.com (Leo Hsu and Regina Obe) — Thu, 13 Dec 2012 22:32:00 -0500

As Hitoshi Hirada mentioned already in PL/v8 is now the richest procedural language , PL/V8 1.3 has been recently released and some of the great new features are automatic conversion of json objects, and ability to write window functions. Not only does PL/V8 allow you to make the most of the native JSON support in PostgreSQL 9.2, but in many cases particularly numeric processing, the speed is much better than what you get with plpgsql. Someone asked us a while back about this and we are hoping to do a demonstration of pl/v8 for numeric processing where you can see the marked difference in speed and perhaps compare with something like PL/R that is also often used for array numeric processing.

For those who are on windows we've compiled PLv8 1.3 for windows 32-bit and windows 64-bit that work with PostgreSQL EDB installs. We haven't had a chance to thoroughly test them yet, so let us know if you find issues. We've saved the last versions we compiled under a different name since some things are not backward compatible between the PLv8 1.1 and 1.3 releases.

We are also hoping to making our windows binary download links more visible. For stop gap fix, we are tagging all the articles concerning things like FDW extensions, PostGIS, plv8 we've compiled for windows under winextensions and accessible from http://www.postgresonline.com/winextensions.php

Windows Binaries and Installers Up for PostgreSQL 9.2: PLV8 and PostGIS 2.0.1

nospam@example.com (Leo Hsu and Regina Obe) — Sat, 22 Sep 2012 16:24:01 -0400

We've recompiled our PL/V8 for windows against PostgreSQL 9.2.0 (both 32-bit and 64-bit) with latest PL/V8 code. This includes the additional LiveScript language, which you can use by doing:

CREATE EXTENSION plls;

New release also includes some bug fixes such as Crash case with non-array in array returning function.

We have also put up binaries and installers for PostGIS 2.0.1 for PostgreSQL 9.2 (32-bit and 64-bit) downloadable from PostGIS website. We haven't deployed the installers to Application StackBuilder yet since we are doing some testing before we release to the masses.

PostGIS 2.0.1 for windows PostgreSQL 9.2 and PostGIS Project changes

nospam@example.com (Leo Hsu and Regina Obe) — Mon, 17 Sep 2012 00:50:00 -0400

A couple of people have expressed concern that we have not released a PostGIS 2.0.1 for Windows 9.2. I guess 9.2 really makes people want to jump and scream for joy. Even if they don't deploy on Windows, Windows is a popular development platform to kick the tires. We originally were planning to not release one and were hoping people would not notice and just start using the PostGIS 2.1.0SVN. That plan evidently did not work. So Yes, we will be releasing a PostGIS 2.0.1 for 9.2 both 32-bit and 64-bit probably late this week. We've got some regression kinks showing in the 9.2 64-bit chain that we are troubleshooting before we release to the masses.

We've been busy beefing up the PostGIS testing and interim build infrastructure to replace the old PostGIS Hudson CentOS build bot. If you are in a super rush and really need a 2.0 micro, you can use the PostGIS 2.0.2SVN binaries, generated by Winnie the PostGIS windows build bot. If you hang around the PostGIS IRC channel, you may have stumbled on Debbie, Winnie's younger and more vocal sister (Debian 64-bit hosted on GoGrid) that does all the document builds and tar balls currently. We are hoping to have Debbie eventually pull PostgreSQL source directly from Git PostgreSQL 9.3, so we can make sure we don't introduce issues for 9.3 along the way and can catch them early.

File FDW Family: Part 2 file_textarray_fdw Foreign Data Wrapper

nospam@example.com (Leo Hsu and Regina Obe) — Wed, 09 May 2012 23:46:00 -0400

Last time we demonstrated how to query delimited text files using the fdw_file that comes packaged with PostgreSQL 9.1+, this time we'll continue our journey into Flat file querying Foreign Data Wrapper using an experimental foreign data wrapper designed for also querying delimited data, but outputting it as a single column text array table. This one is called file_textarray_fdw and developed by Andrew Dunstan. It's useful if you are dealing with for example jagged files, where not all columns are not properly filled in for each record or there are just a ton of columns you don't want to bother itemizing before you bring in. The benefit is you can still query and decide how you want to break it apart. You can grab the source code from file_text_array_fdw source code. If you are on windows, we have compiled binaries in our Bag o' FDWs for both PostgreSQL 9.1 32-bit FDW for Windows bag and PostgreSQL 9.1 64-bit FDW for Windows bag that should work fine with the EDB installed windows binaries. For other systems, the compile is fairly easy if you have the postgresql development libraries installed.

ODBC Foreign Data wrapper - odbc_fdw on windows

nospam@example.com (Leo Hsu and Regina Obe) — Tue, 27 Mar 2012 16:30:00 -0400

One of the new features in PostgreSQL 9.1 that we've been meaning to try is the new foreign data wrapper support. Now that we are in compile mode gearing up for releasing PostGIS 2.0.0 for windows (both 32 and 64-bit), we thought we'd give the odbc_fdw a try trying to compile on windows. Last we tried we weren't successful because we couldn't get past the -lodbc required step.

It turns out there is an easy fix to the ODBC dependency issue and I'm not sure I changed the line right. In the makefile we changed -lodbc to -lodbc32. This was needed for both compiling 32-bit as well as the 64-bit. We compiled the 64-bit version under our Mingw-64 chain and 32-bit under our old Mingw gcc 3.4.5. Sadly we still don't have our mingw64 (compile for windows 32-bit compile up yet). Our ming64 for windows 32 can compile the 9.2 development branch but not the 9.1.3. Go figure. Anyrate to make a long story short -- we have 32-bit binaries for PostgreSQL (you can use in VC++ builds) and 64-bit binaries as well that you can use for the VC++ EDB builds for those who are interested in experimenting. PostgreSQL 9.1 Windows 32-bit ODBC FDW PostgreSQL 9.1 Windows 64-bit ODBC FDW

So far we've tried the PostgreSQL 64-bit data wrapper against a SQL Server 2005 DSN and it seems to work fine. Have yet to try it on other ODBC sources. We'll write up a more detailed article describing how to make the connections.

There is one trick to getting Mingw64 compiled PostgreSQL extensions to work with the Windows 64-bit EDB builds, and that is that when you compile your PostgreSQL under mingw64, you have to configure with option ----disable-float8-byval as we noted in our PostGIS Window 64 build instructions.
