Hi,

After reporting bug#14950 I saw yum updates
available from the pgdg10 repo, and installed those
updates.  Here is the yum log:

Dec 19 10:17:25 Installed: proj49-4.9.3-3.rhel7.x86_64
Dec 19 10:17:25 Updated: ogdi-3.2.0-4.rhel7.x86_64

Dec 19 10:17:29 Updated: postgis24_10-2.4.2-4.rhel7.x86_64


Now, pg_dump fails with the following message:

pg_dump: [archiver (db)] query failed: ERROR:  could not load library
"/usr/pgsql-10/lib/postgis-2.4.so": /usr/pgsql-10/lib/postgis-2.4.so:

    ') AS attfdwoptions FROM pg_catalog.pg_attribute a LEFT JOIN

'46044'::pg_catalog.oid AND a.attnum > 0::pg_catalog.int2 ORDER BY
a.attnum
pg_dumpall: pg_dump failed on database "babase", exiting

Apologies for not reporting the specific command which produces this error.
I believe it is a "pg_dumpall -s", but it might be without the -s.  If this
matters please let me now and I'll get you the exact command.

I tried removing and re-installing the postgis24_10 package, and tried
rebooting the machine.  (Because why not?)  The problem persists.

FWIW, "yum list installed '*geo*'" shows:
