   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   </pre></blockquote><pre wrap="">
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:

</pre></blockquote>    Thank you very much. I've choosen the second option, using this query:<br /><br />        update
pg_castset castcontext='i' where castsource=23 and casttarget=16<br /><br /><br />
