Issue with Postgres database

[ALIP-0]

With postgres configured wgportal creates a number of tables and data, however when i login and goto the interfaces screen no interfaces are shown, despite one being configured in the db table - i get the following error;

Failed to load interfaces: unable to load all interfaces: ERROR: prepared statement "stmtcache_78bc77220c7a756ffad09fd606f629b582d36975c88309a4" already exists (SQLSTATE 42P05)
