I'm writing a function that accepts a table name and digs some information
out about it. I'm developing on 7.3cvs w/schemas, and wanted my function to
use schemas.
If the user gives a full schema name (s.table), I find the table in pg_class
by comparing the ns oid and relname.
However, if the user doesn't give the full schema name, I have to find which
table they're looking for by examining current_schemas, iterating over each
schema in this path, and trying it.
Is there a function already in the backend to return a class oid, given a
name, by looking up the table in the current_schemas path? Would it make
sense for us to expose this, or write one, so that this small wheel doesn't
have to be re-invented everytime someone wants to find a table by just the
name?
Something like:
findtable(text) returns oid findtable("foo") -> oid of foo (given current search path) findtable("s.foo") -> oid
ofs.foo
I can write something in plpgsql (iterating over the array, checking each,
etc.), however, it would be nice if something was already there.
Any ideas?
Thanks!
