Hello All,
Im working on my postgres FDW extension, to support logical replication I
need to use Custom WAL resource manager. In postgres extensions have the
flexibility to register their resource managers in RmgrTable[]. But Like
RmgrTable[] we have another resource manager related table RmgrDescTable[],
there we didn't have the flexibility to register our
1) rm_name
2) rm_desc
3) rm_identify
GetRmgrDesc() are widely used in XLogDumpDisplayRecord() and
XLogDumpDisplayStats() in pg_waldump.c. In function GetRmgrDesc() for
custom resource managers by the default they are assign
1) rm_desc = default_desc
2) rm_identify = default_identify
Suggest some ways to register my own rm_desc and rm_identify in
RmgrDescTable[]?
Attaching the Custom WAL resource managers commit for the reference:
https://github.com/postgres/postgres/commit/5c279a6d350205cc98f91fb8e1d3e4442a6b25d1
Thanks and regards
