--disable-shared is entirely broken these days
A gripe today in pgsql-novice made me realize that configure's
--disable-shared option has been useless since 9.0, because it prevents
plpgsql.so from being built, which causes initdb to fail now that
plpgsql is installed "by default" --- which actually seems to mean
"you don't have any choice about whether to install it".
So, a few questions:
1. Should we honor the promise implicit in the "by default" wording
that there should be a way to initdb without plpgsql?
2. Seeing that this is the first complaint since 9.0, should we decide
that --disable-shared is no longer worth supporting? Seems like we
should either make this case work or remove this switch. I notice
that the switch isn't documented anywhere in the SGML docs, either.
If we do keep it, we'd better document that it results in a severely
crippled version of Postgres.

I can't really imagine the reasons to support this switch at this
time. Compile times are fast, disk space cheap, and if one wanted to
avoid the dynamic linker entirely and use features like replication
(which, IIRC, is dynamically linked for libpqwalreceiver.so) and
plpgsql then people are out of luck without some work of (perhaps?)
questionable value.

I think the last remaining use was the QNX port, which didn't support
shared libraries.
We should just remove it now.

--disable-shared removed, with the attached, applied patch.

I couldn't find any place we document it. I did:
grep _shared *.sgml
and no hits were returned. Should I search for something else?

It's --enable-shared, not --enable_shared. I see at least one hit, in
installation.sgml.

Oops, that text is talking about Python's configure, so I put the text
back. Seemed we had _no_ mention of our own --enable-shared.

Yeah, I just realized the same. Apparently the configure script's
--help output was indeed the only documentation.
