Re: SQL server application porting headache

Hello,

I had similar problem porting an old application from MySQL,
~ solved quoting table/field indentifiers in the create statements,
then made the attached patch.

The patch alter the pgsql query parsing so that you can use insensitive
case names in selects,
but the server give you resultsets with the case you used when creating
tables.

try it on pgsql 7.2, should work....

Of course I'm interested in improving it.

bye
PS the patch also adds the ability to exclude objects from pg_dump with
regular expression match.
