function to_regclass(text) does not exist

What happened?

Hi,

I was using an older version of TablePro (0.53.0); when I updated the application to a newer version (0.54.0 or the latest v0.73.0)... I encountered the following error in the table list (on a PostgreSQL 9.1.23 database):

ERROR: function to_regclass(text) does not exist 
LINE 2: obj_description(to_regclass (quote_ident(t.table_schem. ^ 
HINT: No function matches the given name and argument types. You might need to add explicit type casts. (SQLSTATE: 134)

Thanks anyway for your work; the app is truly perfect.

Steps to reproduce

1. Open a PostgreSQL 9.1.23 connection
2. See the list of tables that crash

Expected behavior

Ability to view the list of tables, even on an older version of PostgreSQL

Database type

PostgreSQL

TablePro version

0.73.0

macOS version & chip

macOS 26.5.2 / Apple Silicon

To add more details: after creating a fallback for to_json, it failed with ERROR: type "json" does not exist.

My database is running on an older PostgreSQL version (< 9.2) that doesn't natively support the json data type. It seems TablePro 0.73.0 relies heavily on modern JSON functions and to_regclass for schema introspection (like listing columns and table metadata), whereas version 0.53.0 worked smoothly on older instances without requiring JSON features.
