In 7.4 I am finding that '(' (and some other punctuation) is not a member of
[:print:]. It is in 7.3. It is a member of [:graph:] in 7.4 (which is
supposed to be [:print:] - [:space:]).
The following is my 7.4 config:
./configure --prefix=/usr/local/pgsql --enable-integer-datetimes --with-pgport=5433
For 7.3 I used:
./configure --prefix=/usr/lib/pgsql --exec-prefix=/usr --with-perl --with-openssl
--mandir=/usr/man --docdir=/usr/doc --enable-integer-datetimes
The following is an example of the problem:
area=> select version();
