Plesk unable to drop database that was dropped and then recreated via command line

[help-please]

Plesk is having trouble dropping a database that was dropped and then recreated using the postgres dropdb and createdb command.

The database was initially created within Plesk. We disconnected it from Plesk somehow when we ran the dropdb and createdb command from the command line. Plesk no longer recognizes the newly created database. If we try to drop the database from Plesk it throws errors. If we drop the database that we created via command line, Plesk still sees the database. I just want to start over and recreate the database in Plesk.

Does anyone know how I can fix this problem?
