EXISTS - Mailing list pgsql-sql

Hi,

I would like to know if this this type of statement can be used in
Postgresql

IF NOT EXISTS (SELECT 1 FROM Table WHERE col1 = 'mystring' )
BEGIN
...
END

If it can, any idea why I get this error.
********** Error **********

ERROR: syntax error at or near "IF"
SQL state: 42601
Character: 2


Thanks
