Thanks, nice explanation :)

The question is: How can I enable several users to define a complete
substitution syntax for getting a username from a database name (after a
fixed scheme)? I thought I could resolve that by loading a config file
where the users can specify a substitution syntax after a certain scheme
(one scheme for all databases of one user, but different between various
users).
E.g. I have a database name "PRODDB"/"TESTDB"/"BUILDDB" --> username is
"prod"/"test"/"build" (s/db$//g)
E.g. I have a database name "STGKK_STP15M3"/"NOEGKK_STP14T2" -->
username is "stp15m3"/"stp14t2" (s/^[a-z*]_//g)
(always after a 'tr [A-Z] [a-z]')
Cheers,
Nora
