I cannot reproduce your problem at hand on HEAD or REL_11_STABLE,
though I can get the same place as you do.  The error message is very
specific to varlena.c or regproc.c, so that's a clear hint, but I am
wondering what's wrong.

Do you have anything specific in that?


Thank you. 
Actually I did not event create this file /home/appli3/appli/connexion/dbaappli3/custom/postgresql_custom.conf    (just set the parameter in case of).

I put the debug5 logs of potgres above (previous ones where INFO level)
Also we use systemd so I launched PostgreSQL with pg_ctl directly : same behavior (an error)
