RES: Diferences between functions criated in pg 8.0.4 and criated in pg 7.4.8

Martijn :

OK, y try to explain.

First, y im using phppgAdmin for do this operations, becous my systems are
all web based.
My developpement plataform is windows, and this is the reason of use pg
8.0.4.

1) I change :

CREATE OR REPLACE FUNCTION LEFT( sTexto CHARACTER VARYING, nPosFin INTEGER )
for :
CREATE OR REPLACE FUNCTION LEFT( CHARACTER VARYING, INTEGER )

Becouse in the online documentation of pg 7.4 does not has other syntax for
parameters.

2)

RETURNS "varchar" AS $$ --> Syntax error here.

I change the function to

CREATE OR REPLACE FUNCTION LEFT( CHARACTER VARYING, INTEGER )
RETURNS "varchar"
LANGUAGE plpgsql
CALLED ON NULL INPUT
SECURITY INVOKER
AS '
BEGIN
IF sTexto IS NULL OR nPosFin IS NULL OR nPosFin <= 0 THEN
RETURN '';
ELSE
RETURN SUBSTR( sTexto, 1, nPosFin );
END IF;
END;
';

At this point i have sourprice. The hosting say does no exist 'plpgsql'

This last syntax has error, but i can't find.

Can you help me ?
