    <pre wrap="">   Hello everybody.

    I''ve just converted an access database to postgres. The conversion
was ok, but when i'm trying to insert data on some tables with boolean
types from a Visual Basic application i receive an error. A sample:

    table example, with firs field of integer, second of type text and
third of type boolean

    the query: INSERT INTO EXAMPLE VALUES (1, 'text', 0)

    When i used access this worked fine, in boolean types 0 is false and
1 is true, but in postgres (8.1 and 8.3 version) i receive the next error:

    column "premarco" is of type boolean but expression is of type integer

    My question is, can i force postgres to accept integer values as
boolean without changin query to INSERT INTO EXAMPLE VALUES (1, 'text',
0::boolean). This is a problem because if I have to do this i will have
to test about one hundred queryes

    Thank you very much

Two options:
1) Change the column in Postgres to an integer type.
2) Change the assignment in pg_cast from explicit  to implied for the 
int4,bool cast. See for more details:

&nbsp;&nbsp;&nbsp; Thank you very much. I've choosen the second option, using this
&nbsp;&nbsp;&nbsp; &nbsp;&nbsp; update pg_cast set castcontext='i' where castsource=23 and
