¿Complicado?
http://www.postgresql.org/docs/view.php?version=7.3&idoc=1&file=plpgsql-control-structures.html#PLPGSQL-CONDITIONALS
-----------------------------------
19.6.2. Conditionals
IF statements let you execute commands based on certain conditions.
PL/pgSQL has four forms of IF:
*
IF ... THEN
*
IF ... THEN ... ELSE
*
IF ... THEN ... ELSE IF and
*
IF ... THEN ... ELSIF ... THEN ... ELSE
-----------------------------------
Exactamente igual ;-)
