-----------------------------------
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 ;-)
