I know. I was asking in principle, whether a
felt-to-be-more-proper change in pg_dump/pg_restore for
handling default_transaction_read_only can be hoped to happen
or not (short of submitting a patch).
For the record: The kludge I have implemented now is this
CMD_PG_RESTORE="pg_restore --create --file=- ${BACKUP}.dir"
CMD_PSQL="psql --echo-errors --dbname=template1 --port=${GM_PORT} --no-psqlrc"
CMD_SUDO="sudo --user=postgres"
{
${CMD_PG_RESTORE} | grep --ignore-case --invert-match --regexp="alter database ${TARGET_DB} set
default_transaction_read_onlyto.*on" - | ${CMD_SUDO} ${CMD_PSQL}
} &>> "${LOG}"
which I am sure can be improved (such as, I was unable to get
the quoting right for factoring out the grep from the
pipeline :-)
I would be happy to hope that pg_dump might gain knowledge to
skillfully emit
alter database ... default_transaction_read_only to 'on'
only after having emitted any data-loading statements or else
gain a --do-not-alter-database-to-read-only effectively
omitting said statement thereby allowing for a more elegant
treatment of the issue.
Best,
Karsten
