Current and ongoing tools

  • pg_dump
  • pg_dumpall
  • barrier and PITR

Also, for upgrade, it is very probable to use pg_upgrade for our purpose.

What is missing

We need means to upgrade GTM. GTM holds restart data for GXID and sequence. Future upgrade could not be compatible and may need to convert gtm.control. We need dump/restore tool of gtm.control in such case.
