This is an unfortunate predicament that many people find themselves in and does cause a bit of frustration. You bring in some tables into your PostgreSQL
database using some column name preserving application, and the casings are all preserved from the source data store. So now you have to quote all the fields
everytime you need to use them. In these cases, we usually rename the columns to be all lower case using a script. There are two approaches we have seen/can think of for doing this
one to run a script that generates the appropriate alter table statements and the other is to update the pg_attribute system catalog table directly.
