Update table view based on the selected postgres db

[gaborpongracz]

As far as I see, in case of Postgres plugin, dbgate TABLES, VIEWS, FUNCTIONS section not updated based on the selected postgres DB, but showing all the available table from all the databases within the postgres instance.

Adding the #DATABASE# filter into the tableList.sql this problem could solved.

@janproch Could you check this out? Should I update other queries with this WHERE clause too?

I've just checked the latest version with server/port/user/pwd configuration instead of the database_url and seems working like a charm. So not the sql was the real issue but the connection with db url. Should I create an issue for this and close this PR?

[janproch]

Maybe there is not specified database in dburl? If you provide dburl with database specified, does it work correctly?

seeing this too: when connecting with a URL string I cannot see tables, etc, of a db with a large-ish (100+) list of db's. Smaller db servers seem to be working ok
