dbtoyaml Fails When PG Password Has Spaces (Improper Escaping)

[benjamin-kirkbride]

How to reproduce:

1. Create PD DB with role with a password with spaces
2. Try to connect

Example:

$ python -m pdb -c continue .venv/bin/dbtoyaml -H db.REDACTED.supabase.co -U postgres --password postgres
Password:

As you can see from the last line, the password is not properly escaped.

If I had to guess this could be reproduced even without actually even configuring a PG DB with a password with spaces.

I have confirmed that everything works if the spaces are removed from the password.

I had never heard that spaces were allowed in passwords!

Technically, however, this is a bug in pgdbconn rather than Pyrseas. It doesn't escape any of the parameters. Which brings me to another issue of moving forward with Pyrseas. Way back when, I thought that having pgdbconn as a separate repo was a good idea, because eventually (if a concurrent user app was to be supported), we'd need more than simple connection management. Currently, I think if Pyrseas is to move forward, on Python, pgdbconn ought to be folded back in.
