Drat. I was really hoping that you'd just forgotten initdb --- the
parsetree changes I made a couple weeks ago could have explained this,
but not if you initdb'd.
The failure is presumably coming from an attempt to read a stored rule
or default-value clause that's not stored in the format that the read
procedures are expecting. I'm guessing that there is a node write proc
that's not the inverse of the corresponding node read proc, and you
happen to have a rule or default that has the right kind of node in it
to expose the bug.
Could you burrow in with a debugger and find out more about the rule or
default that's triggering the error?
