commit b4307ae2e54 (HEAD, upstream/master, upstream/HEAD, master) Author: Dean Rasheed <[email protected]> Date: 2026-01-24 11:30:48 +0000 Fix trigger transition table capture for MERGE in CTE queries. ... This requires changing the TransitionCaptureState structure, replacing "tcs_private" with 3 separate pointers to AfterTriggersTableData structures, one for each of INSERT, UPDATE, and DELETE. Nominally, this is an ABI break to a public structure in commands/trigger.h. However, since this is a private field pointing to an opaque data structure, the only way to create a valid TransitionCaptureState is by calling MakeTransitionCaptureState(), and no extensions appear to be doing that anyway, so it seems safe for back-patching. ... In [1] Dean said he's expects to have to push an amendment to .abi-compliance-history soon. But then the discussion got a bit derailed because one of the complaints being reported is bogus, as the struct is only defined in a .c file.
