Getting error `'str' object has no attribute 'parent'`

Description

Getting error 'str' object has no attribute 'parent' for any command that I run

Your environment

• Please provide your OS and version information. Manjaro Linux
• Please provide your CLI version. 3.2.0
• What is the output of pip freeze command. I’m using pgcli inside of a virtual environment (in a directory called /dev/data/pytools/pgcli, and /dev/data/pytools/pgcli/pip freeze gives the following output:

cli-helpers==2.2.0
click==8.0.3
configobj==5.0.6
pendulum==2.1.2
pgcli==3.2.0
pgspecial==1.13.0
prompt-toolkit==3.0.24
psycopg2==2.9.3
Pygments==2.11.2
python-dateutil==2.8.2
pytzdata==2020.1
setproctitle==1.2.2
six==1.16.0
sqlparse==0.4.2
tabulate==0.8.9
wcwidth==0.2.5

I enabled DEBUG logging for pgcli, and I see the following trace back:

During handling of the above exception, another exception occurred:

Not sure what happened TBH. It was working before and suddenly I’m getting the error

UPDATE: after investigating, the issue seems to come from the latest release 2.11.2 from pygments. Downgrading to 2.11.1 removes the error

For anyone coming to this who’d just like a temporary workaround so they can run some queries with pgcli–the expanded display still works. You can switch to it with \x.

@Anteru I see your comment on the PR. I’ll take a stab at fixing it in cli_helpers.
