Given the location of the error, it seems like you might have a
problem with inconsistent ABI for "flex". I'm not quite sure
how you'd get there, because that's usually pretty self-contained.
(Once there was a "libfl.a" that could possibly cause this sort of
problem, but I don't think that exists in modern flex versions.)
Anyway, I'd check that you have a consistent installation of flex
and then rebuild Postgres from source.
regards, tom lane
