True, its foggy behave. Only if block contains exception than variables
SQLSTATE and SQLERRM are created.

This name use Oracle in PL/SQL. ESQL Oracle and DB2 too. I think so is
better use well knowed names for it than creating own. There is one argument
for it. PL/pgSQL is language very similar Oracle PL/SQL. PL/SQL know
SQLERRM, SQLCODE and SQLSTATE. An people which know PL/SQL will like use
this names in Pg.
