Thanks Alvaro, for the info…

Hi Team,

Please find the attached patch.

Apart from the AIX specific changes, there is a minor change in this file wrt to XLC, below is the error for which we removed inline.
Later, the build and tests passed for both XLC(16.1.0.18) and gcc(12) as well.

  src/backend/storage/buffer/bufmgr.c

  "bufmgr.c", line 811.39: 1506-780 (S) Reference to "RelationGetSmgr" with internal linkage is not allowed within inline definition of "ReadBufferExtended".
  "bufmgr.c", line 811.15: 1506-780 (S) Reference to "ReadBuffer_common" with internal linkage is not allowed within inline definition of "ReadBufferExtended".
  gmake[4]: *** [<builtin>: bufmgr.o] Error 1


Please let us know your feedback.

Thanks,
