Resolves issue where tag filtering in PostgreSQL databases failed with "operator does not exist: jsonb ~~ unknown" error. The hierarchical tag filtering feature introduced in commit 5e47f25b generated SQL with implicit type placeholders that PostgreSQL couldn't infer.
The fix explicitly casts the LIKE comparison placeholder to text (::text) in the PostgreSQL dialect, ensuring proper type resolution for the query parameter.
