Re: oauth support?

I'm reading about the new OAuth support in PostgreSQL 18. It says 
PostgreSQL needs to be built using "--with-libcurl".

In the PostgreSQL I get when using apt.postgresql.org, I don't see 
anything about curl in output from "ldd 
/usr/lib/postgresql/18/bin/postgres", nor from "ldd 
/usr/lib/postgresql/18/bin/psql".

Should I expect to be able to use the new OAuth feature in PostgreSQL
18  with the packages from apt.postgresql.org? If so: Do I need to
install a particular, extra package for it to be available?

OAuth support is in the libpq-oauth (sub)package. RPMs also split that
into -libs-oauth subpackage for security concerns over curl.

    Hi.

    From what I can see, the package libpq-oauth contains the file:

/usr/lib/x86_64-linux-gnu/libpq-oauth-18.so

which is dynamically loaded by Postgres, see https://github.com/postgres/postgres/blob/master/src/interfaces/libpq/fe-auth-oauth.c#L818

    WRT libcurl, it's not linked but shows in pg_config:

$ pg_config |grep -o "with-libcurl"
with-libcurl
