I try to make a DB diagram of a postgresql database using eralchemy version 1.2.7 and I get the following error:

I believe this is related to the usage of citext extension in on db table. You can find more info about citext here [1] but I believe that for this project those can be consider text fields.

The command was simple:
eralchemy -i postgres://db:dbpassword@172.17.0.1/portal?sslmode=disable -o schema.png

I too see a similar issue using citext.

/lib/python3.9/site-packages/eralchemy/sqla.py:84: SAWarning: Did not recognize type 'citext' of column 'name'
  Base.prepare(engine, reflect=True, name_for_scalar_relationship=name_for_scalar_relationship)

Is there a way around this?

ERAlchemy: 1.2.10
Python: 3.9.2
