Using SHOW in PL/pgSQL

Hi everybody

I have a brief question. It it just a simple yet annoying problem.
How can I use SHOW to retrieve a value inside a PL/pgSQL function?

I am looking for something like that:

SELECT enable_seqscan;

Is there a system table where I can find all the values on 7.2.3?
It seems as if there was no way to use SHOW in a subselect.

Any ideas to solve this problem efficiently.

    Hans

In 7.3 there are SQL function calls equivalent to SHOW and SET.
I think using those is probably the only way, short of hacking on
plpgsql.
