That's because the SELECT INTO variable and SELECT INTO record syntax
are confusingly different.  It's

for records:
SELECT INTO record_var * FROM ...

for simple variables:
SELECT column INTO variable FROM ...

I'm not clear on the origin of the inconsistency; my guess is that jan
copied it over from PL/SQL.

You should *always* do this.  Most functions with identical column and
variable names will confuse the compiler and result in errors.

It'd have been nice if PL/pgSQL supported variable naming with a special
character preifx (e.g. $variable).  Does anyone know of a character that
won't give the parser fits?  Currently I'm using "v_", same as Richard.
