You can try to change the queries in the ini file to something like this...
But this one does not do anything about the numeric_precision for example.
query_tablecols = SELECT attnum as ordinal_position,
quote_ident( attname ) as column_name,
format_type(atttypid,atttypmod) as data_type,
( select pg_get_expr(adbin, attrelid) from pg_attrdef where adrelid = attrelid and adnum = attnum )::text as column_default,
not attnotnull as is_nullable,
nullif( attlen, -1 ) as character_maximum_length
NULL as numeric_precision
WHERE attrelid = '%s'::regclass::oid
AND attnum > 0
AND NOT attisdropped
ORDER BY ordinal_position;
query_tables = select oid::regclass::text from pg_class where relkind = 'r'::"char"
