The A2 Hosting installation of phpPgAdmin is bogus.
There is no way to login.
Do everything from psql.

  psql -U voyccom_jhagstrand -d voyccom_mai
  password is in .pgpass
  \h list SQL commands
  \? list psql commands
  \dt list tables in public schema
  SELECT * FROM information_schema.tables WHERE table_schema = 'mai';
