 Description  « Hide
Curently, subselects can't be used as PSQL expressions, and all these constructions result in error:
var = (select ... from ...);
if ((select ... from ...) = 1) then
if (1 = any (select ... from ...)) then
if (1 in (select ... from ...)) then

These are all potentially valid expressions. Now the user need to write independents SELECT ... INTO without any advantage.
