Type typo in parameter of pgsql function

Hello all

This patch fixes a small error in the Porting PL/SQL to PL/pgSQL
section where a instr function parameter is mistyped as varchar. It
works properly when changed to integer.

This is only my second patch. I generated it using cvs diff -c
filename. If I've bungled the format, please let me know.
