Hi Amit.

PSA the v19 patch for the Tablesync Solution1.

Main differences from v18:
+ Patch has been rebased off HEAD @ 24/Jan
+ Addressing some review comments [ak0123]

====

Features:

* The tablesync worker is now allowing multiple tx instead of single tx.

* A new state (SUBREL_STATE_FINISHEDCOPY) is persisted after a
successful copy_table in tablesync's LogicalRepSyncTableStart.

* If a re-launched tablesync finds state SUBREL_STATE_FINISHEDCOPY
then it will bypass the initial copy_table phase.

* Now tablesync sets up replication origin tracking in
LogicalRepSyncTableStart (similar as done for the apply worker). The
origin is advanced when first created.

* The tablesync replication origin tracking record is cleaned up by:
- process_syncing_tables_for_apply
- DropSubscription
- AlterSubscription_refresh

* Updates to PG docs.

* New TAP test case.

Known Issues:

* None.
