  1. Restore AIX support.

  2. pg_createsubscriber: Improve error messages.

  3. Use <stdint.h> and <inttypes.h> for c.h integers.

  4. Stabilize jsonb_path_query test case.

  5. Fix C23 compiler warning

  6. pg_stat_statements: Add tests for nested queries with level tracking

  7. Add missing newline at the end of index_including.sql

  8. Remove AIX support

  9. Fix s_lock.h PPC assembly code to be compatible with native AIX assembler.

  10. Use a non-locking initial test in TAS_SPIN on PPC.

  11. Use LWSYNC in place of SYNC/ISYNC in PPC spinlocks, where possible.

  12. Use mutex hint bit in PPC LWARX instructions, where possible.

  13. Adjust TAS assembly as per recent discussions: use "+m"(*lock) everywhere

  14. Apple's assembler likes the inlined TAS syntax too, so no reason to

  15. Tighten up register usage for inline PPC version of tas().

  16. Put the isync where it's supposed to be.
