autovacuum parameters

Hi,
it is possible to set autovacuum_analyze_threshold
and autovacuum_analyze_scale_factor for TOAST tables using pgAdmin.
Script generated is like this:

ALTER TABLE "MySchema"."MyTable" SET (
toast.autovacuum_analyze_threshold = 50,
toast.autovacuum_analyze_scale_factor = 0.1
);

according to doc
http://www.postgresql.org/docs/9.1/static/sql-createtable.html#SQL-CREATETABLE-STORAGE-PARAMETERS
there
is no corresponding autovacuum_analyze_threshold
and autovacuum_analyze_scale_factor for toast tables, and PG generates
error when OK button is pressed - what is expected.

My suggestion is to disable/remove these options in Toast Table tab in
Table Properties dialog.

BTW. When Custom autovacuum is enabled and there are no custom values set,
then -1 is displayed - fields where empty in previous versions

Environment:
pgAdmin III 1.14.2 Win 7 32 bit
PG 9.1.3 MS Server 2008 R2 64 bit

Bartek
