I suspect this is the same problem that was reported by Jehan-Guillaume
de Rorthais, for which there are two patches proposed, his and mine:

[1] https://postgr.es/m/202408072250.2c4fkhwf56lk@alvherre.pgsql
[2] https://postgr.es/m/20240905005728.0836d609@karst

I haven't looked at his patch, but I suspect it's better than mine on
maintainability grounds.  I think his code causes more catalog churn,
though perhaps we don't care too much about that in this particular
case.
