Actually, this argument is based on a false premise anyhow. I took
a look into Debian's source package, and AFAICS they are not doing
anything as weird as a run-time substitution. They are just filling
the build environment with libedit-dev not libreadline-dev. So that
is certainly a supported configuration from our side, and if there
is any header-to-library discrepancy then it's just a simple bug
in the libedit package.

(Maybe at one time they were doing something weird; I didn't look
back further than the current sources for PG 12.)
