PG SQL and LIKE clause - Mailing list pgsql-general

Hello,

We're porting a huge Library Management System, written using all kind
of languages one can think of (C, C++, ESQL/C, Perl, Java, ...) on Linux
from the DBS Sybase to PG, millions of lines of code, which works also
with DBS Oracle and in the past with INFORMIX-SE and -ONLINE.

We got to know that in CHAR columns with trailing blanks a 

SELECT ... FROM ... WHERE name LIKE 'Ali'

does not match in 'name' having 'Ali '.

I glanced through our code with grep pipelines and found some hundred
places which would be affected by this problem. I'm not interested in a
religious discussion if or if not this behaviour of PG is correcter or
better than in Sybase. It's just different to Sybase.

Any hints to address this problem? Or is there any compile time option
for the PG server to address this?

Thanks
