[pgAdmin][RM4842] trigger/compound trigger on a partitioned table

Hi Hackers,

Attached is the patch to fix the issue where it was not possible to add
constraints, index, rules, triggers and compound triggers on child tables
of a partitioned table.
The problem was with URLs formed which also included parent table OID,
which was not needed. The code is changed to add "url_jump_after_node"
param to skip after a certain node, which will will skip all the value
between jump_after_node to the last node, excluding jump_after_node and the
last node. Partitioned table itself is a "table" and can be multilevel.

Kindly review.
