Description:        insert into table (column) values (nullif('',''));
Details:

insert into table (column) values (nullif('',''));
ERROR: column "column" is of type boolean but
expression is of type text.

inserting NULL works. nullif('','') should return NULL
if both values are equal? It works in MSSQL.

Is there different function to accomplish a insert
nullif('','') test.

Thanks
Matt
