Here's what I can add over the past few days:
- Almost all failures are either reltuples=48 or SIGABRTs
- Almost all SIGABRTs are DDLs - CREATE INDEX / CREATE AGGREGATEs / CTAS
  - A little too coincidental? Recent crashes have stack-trace if
interested.

Barring the initial failures (during move to gcc 13.2), in the past week:
- v15 somehow hasn't had a failure yet
- v14 / v16 have got only 1 failure each
- but v12 / v13 are lit up - failed multiple times.
