List pgsql-odbc

Hi Dave,
I just started using the PG odbc driver with access and I noticed that the only schema that would show up was public, even though I had added several of my own that are visible.
The only way I could get it to work was with the searchpath, and that does not seem to me how it should work.
The search path is a marginal solution because if you add new schemas you have to update every single DSN with the new search path, this can be alleviated some by using a file DSN but it is still a huge PITA.
I was using the stable version from Nov 2003

Thanks,

[ODBC] Schema support





There have been a couple of reports that psqlODBC does not support
schemas. This is not strictly true, it actually has full support for
schemas, however, SQLTables honours the search_path variable on the
server and hides objects in schemas that are not visible.

I'm not convinced this is the correct behaviour - SQLTables should show
everything afaict, unless a parameter is passed to it to filter the
output. The micro-patch below corrects this - however I'm not 100% sure
there won't be any side effects I haven't thought of. I'd appreciate it
if I could get some feedback.

Thanks Dave.
