#3702 PostgreSQL overloaded functions support

[Wouter van Nifterick]

In PostgreSQL, you can have overloaded functions (same name, different arguments).

Multiple overloaded functions appear in the DBTree, but no matter which one you select, you'll always get the same one.

I guess that's the reason why PgAdmin shows functions including their argument types, like this:

functionX(bigint)
functionX(bigint,t_context)
functionX(bigint,t_context,boolean)
functionY(bigint)
etc.

By the way, I'm very happy to have at least basic PostgreSQL support in Heidi, because once you're used to the awesomeness of Heidi's grid editor, it's difficult to settle for the crappy grids in other clients.
