David,
Thom,
Problem is solved right now (just a minute ago) - the real reason seems
to be multilanguage support of PgAdmin.
Im using Polish (actually 'default') language version according to the
OS settings and have just switched to English language for a while to
ensure the options you've written in previous mails where identified
correctly by me in Polish but surprisingly I found then that 'Jobs' node
is already present.
When I've switched back to Polish, it disappears again, thus I
anticipate this is a bug in PgAdmin on multilanguage support.
Thank you for your support,
Piotr
