third server pages - waits for user 'q' to switch back to shell prompt. None of the servers - no that I could find - has $PAGER nor $PSQL_PAGER nor $SYSTEMD_PAGER set. In fact:
-> $ set | egrep -i page -> $ env | egrep -i page
shows nothing. None of the servers - I failed to find - has psqlrc, not for the user nor system-wide. On the two non-paging servers with this: -> $ psql --port=5437 -c '\pset pager on' Pager is used for long output.
done, the above query does not page - for the output is not long enough I believe. On the third paging server - that does not change behaviour neither. But I also noticed that after 'on/off' - this does not change and remains: -> $ psql --port=5437 -c '\pset' | egrep -i pager pager 1 pager_min_lines 0
Should that change/setting not be permanent, at least for the session-time being?
