Tsvector values are not automatically calculated

Query goal: Find base table columns with tsvector type in case of which it is not a generated column nor does the table has an associated trigger to calculate the tsvector value automatically.
Query type: Problem detection (Each row in the result could represent a flaw in the design)
Query reliability: Medium (Medium number of false-positive results)
Query license: MIT License
Fixing suggestion: Use a trigger or a generated column to calculate the tsvector values automatically.
Data source: INFORMATION_SCHEMA+system catalog
