Hi, In the "View/Edit Data" grid, editing a char(n)[] or varchar(n)[] cell triggers a psycopg error: "argument formats can't be mixed". This seems to be the same issue reported in #4410 <https://redmine.postgresql.org/issues/4410>.
Looks like the cause is a format() template which is using "%s" instead of
"{}", leaving a literal "%s" in the generated SQL. Patch attached.
Cheers,
Nick
