Bug reference: 1267
Logged by: Colin Chapman
Email address: c0linchapman@btinternet.com
PostgreSQL version: 8.0 Beta
Operating system: fedora linux
Description: Suggest TEXTOID parameters be treated like UNKNOWNOID
Details:
postgresql-8.0.0beta2
JSP likes to transfer data in parameters as text. When putting values into
a int column you get exception
this can be demonstrated by.
create table d ( numb int );
insert into d values ( '1' );
insert into d values ( '2'::text );
drop table d;
