Best guess is /home/jkregloh/pg_data/data/drupal_dbspace/ is pointing
back to /usr/local/pgsql/data in the other jail.

And /usr/local/pgsql was re-initdbed with a 9.0 cluster, because
previously it was the 9.3 cluster?

And you are sure /usr/local/bin has the 9.3 binaries?

Personally I would say at this point the relationships between versions
are so confused it would seem best to start from scratch.

My suggestions:

1) Create a new jail with a copy of the test 9.0 cluster located in
/usr/local/pgsql.

2) In that jail install a new 9.3 cluster using the --prefix= switch to
configure to have it install in a different location in the jail.

3) Use pg_upgrade.
