When we export char columns with our Perl tools, they come out with trailing blanks (in Sybase they don't). Can this be suppressed?
Switch to varchar, perhaps?

Sometimes people does not know, what they propose. We have a historical
25 years grown ILS which runs on top of Sybase, Oracle, Informix ... and
should now be ported to PostgreSQL. We can't simple switch internal
table structures and adopt some 10.000.000 lines of code (or debug while
it is now crashing).
That was not mentioned in the original post. Anyway:

"ChopBlanks
Type: boolean, inherited
The ChopBlanks attribute can be used to control the trimming of trailing
space characters from fixed width character (CHAR) fields. No other
field types are affected, even where field values have trailing spaces.
The default is false (although it is possible that the default may
change). Applications that need specific behaviour should set the
attribute as needed.
Drivers are not required to support this attribute, but any driver which
does not support it must arrange to return undef as the attribute value."
Thanks anyway.
