another thing i tried to do was: create or replace function lafecha(timestamp with time zone) returns date as 'select date($1);' language 'SQL' with iscachable; But i got the message: ERROR parser: parse error at or near "iscachable"; if avoid "with iscachable" string the fucntion was created succesfully. erobles wrote: > erobles wrote: >> Hello there! >> >> i tried to create an functional index like this: >> >> create index estdistfecha on estadist (date(fecha)); >> >> >> but only get the next message: >> ERROR: DefineIndex: index function must be marked iscachable. >> >> So, How can i mark the date function iscachable ? :-) >> >> i hope your anwsers, anyway thanks to read this ! >> >> >> > >

Egad, what are you running? That message hasn't been spelled that way
