Any chance pg_dump (and/or pg_restore) might gain an option
--ignore-read-only ? That way, PostgreSQL need not decide
for users.
How about:
1) pg_dump -Fc -d read_only_db -U postgres -f read_only.out
2) In new cluster:
A) psql -d postgres -U postgres
CREATE DATABASE read_only;
B) pg_restore -d read_only -U postgres read_only.out
C) psql -d read_only -U postgres
alter database read_only SET default_transaction_read_only TO 'on';
That would work but does not lend itself well to a fully
scripted pg_dump/pg_restore backup "solution". The full
pg_dump command line is this:
pg_dump --verbose --format=directory --compress=0 --column-inserts --clean --if-exists --serializable-deferrable "${_PG_HOST_ARG}" "${_PG_PORT_ARG}" --username="${GM_DBO}" -f "${BACKUP_DATA_DIR}" "${GM_DATABASE}" 2> /dev/null
Wouldn't the below just require the following changes?:
And this is the restore:
sudo -u postgres psql -d postgres -f create_database.sql
sudo -u postgres pg_restore --verbose --create --dbname=template1 --exit-on-error -p ${GM_PORT} ${BACKUP}.dir/
Remove --create and change dbname to the database name from
create_database.sql
sudo -u postgres psql -d <dbname> -f alter_database.sql
At this point version 14 is past the point of adding new features and 15
is 1+ year out, so there is going to have to be some sort of kludge.
Thanks,
Karsten
