We have all the setup executables for PostgreSQL 8.4-9.2 32-bit and
PostgreSQL 9.1-9.2 x64-bit for PostGIS 2.0.3. We'll have the 9.0x64-bit
ones up shortly but do have the binaries.
We are planning to release these to stackbuilder sometime next week, but
would like some feedback first with any issues people run into.
One person already reported a serious bug in our original packaging which we
fixed. If you already installed 2.0.3 the x64-bit version or any of the 9.2
versions (both x32 and x64) that was not marked as -2.zip, -2.exe, you'll
want to reinstall. The 8.4-9.1 32-bits were not affected so just have a -1.
