-- pg_trickle 0.87.15 -> 0.87.16
--
-- v0.87.16 changes newly created/rebuilt identity-bearing relations from the
-- legacy BIGINT digest to the complete V2 BYTEA encoding. Existing V1 state is
-- deliberately not converted in place: v0.87.17 recreates stream tables and
-- buffers from unchanged sources, so a failed upgrade cannot leave a partially
-- converted relation behind.

-- Fail closed until the new binary has rebuilt every identity-bearing state
-- relation and has written both version markers atomically. The old physical
-- relations remain untouched and are rejected by the V2 runtime validator.
