Thread: pgsql: Avoid using NAMEDATALEN in pg_upgrade

Avoid using NAMEDATALEN in pg_upgrade

Because the client encoding might not match the server encoding,
pg_upgrade can't allocate NAMEDATALEN bytes for storage of database,
relation, and namespace identifiers.  Instead pg_strdup() the memory and
free it.

Also add C comment in initdb.c about safe NAMEDATALEN usage.
