There are a couple of small gotcha.
eg.
- PHP actually is case sensitive so:
$row['MyRow'] != $row['myrow']
If you used camel case in pg without quotes it will be a pain.
- Some pg functions aren't case-proof eg. pg_get_serial_sequence
I'm thinking to write a script to quote all identifiers... but I'm
worried it will look to much as a parser rather than a simple sed
script since I got trapped by the above too.
