Hi,

Attached is a patch to fix a very trivial issue of the documentation.

The documentation of PL/pgSQL provides sample codes of Oracle-compatible
instr functions. However, the behaviour is a little differet.
Oracle's instr raises an error when the forth argument value is less than
zero, but the sample code returns zero. This patch fixes this.

Regards,
