Bug reference: 12458
Logged by: Thomas Neumann
Email address: tneumann(at)users(dot)sourceforge(dot)net
PostgreSQL version: 9.4.0
Operating system: Linux 3.16
Description:
The following two queries return different results:
select 'A'::char(1)='A '::text;
select 'A'::char(1)='A '::varchar(10);
I would expect both queries to return "true", and this is also suggested by
the documentation (section 8.3.), but the text comparison returns false.
