I'm having trouble getting Postgres 6.5.3 to do what I want. The problem seems
to be fixed in version 7, but I could really do with a workaround for 6.5.3,
since I'm stuck with that for the time being.
journals2=> create table vc(v varchar(9), c char(9));
CREATE
journals2=> insert into vc values('abc','abc');
INSERT 1631143 1
journals2=> select * from vc where v::char(9)=c;
ERROR: Unable to identify an operator '=' for types 'varchar' and 'bpchar'
You will have to retype this query using an explicit cast
Surely I did use an explicit cast? The same thing happens whether I cast one
side or the other or both. Let's try being sneakier:
journals2=> select * from vc where v::text::varchar=c::text::varchar;
pqReadData() -- backend closed the channel unexpectedly.
This probably means the backend terminated abnormally
before or while processing the request.
We have lost the connection to the backend, so further processing is
impossible. Terminating.
That's obviously too sneaky.
