Hello everyone,

i get error message

ERROR: IN types character varying and integer cannot be matched

whitch is ok (ive read about this restriction in 8.2.x)

but why after

SELECT * FROM s_skladnik WHERE kod IN (902)
or
SELECT * FROM s_skladnik WHERE kod = 902

I dont get error but query gives me correct result ?
