Re: [Npgsql-general] Get function OID and function calling support

Sorry, don't know. Can anyone on pgsql-hackers tell us the purpose of

It's used to invoke the "fast path" function call code
(src/backend/tcop/fastpath.c). libpq's large-object routines use this,
but little else does AFAIK. The current protocol is sufficiently broken
(see comments in fastpath.c) that I'd not really encourage people to use
it until we can fix it --- hopefully that will happen in 7.4.

PS: what in the world is npgsql-general@gborg.postgresql.org ... is that
a real mailing list, and if so why? It sounds a bit, um, duplicative.

OK, Thanks.

npgsql-general@gborg.postgresql.org is the general discussion list for
the Npgsql project on Gborg. It's a .NET data provider for PostgreSQL
that works with .NET programs written in MS VC++, C# or VB.NET not to
mention Mono.

Not to be confused with pgsql-general :-)

Regards, Dave.

San someone point me to what exactly is planned for the
protocol/networking stuff? Networking/protocols is one of my fortes and
I believe that I could actually help here.

Regards,

Greg

TIP 2: you can get off all lists at once with the unregister command
(send "unregister YourEmailAddressHere" to majordomo@postgresql.org)

Ok, as Kristis already said about how functions are being commonly called, I
will implement it this way: transforming the function call into a "select
<function_name>" statement. I already have some working code and I will clean
it and commit it soon.

Thanks all!
