Personally, I would get that new build in a new directory, make sure that it
works with a PITR restore (or directory tree copy while the database is
stopped) of one of the other 9.1 clusters, and make sure you can CREATE
EXTENSION plperl before trying to convert this 7.3 database. Then you can
move all the old clusters over to the new executable by updating your
service script to point to the new executable running stop and then running
start. (I have found that restart does not work for a minor upgrade -- a
separate stop -w and start -w is needed.)

Thanks Kevin,

From the /home/ellerines/pgsql9_upgrade/postgresql-9.1.9/config.log file it
shows that when it was configured , only the prefix was specified in the
configure command.

/home/ellerines/pgsql9_upgrade/postgresql-9.1.9/config.log shows the
following in the beginning:

It was created by PostgreSQL configure 9.1.9, which was
generated by GNU Autoconf 2.63. Invocation command line was

$ ./configure --prefix=/usr/local/pgsql9

with_perl='no'
perl_archlibexp=''
perl_embed_ldflags=''
perl_privlibexp=''
perl_useshrplib=''

I think it's safe to re-build it by including --with_perl and the same
prefix option which was specified.
