Hi, I am trying to schedule pg_cron to generate a set of commands and then
run them. E.g select 'vacuum freeze '||table_name from inventory_for_vacuum
\gexec . This works well at command line, but when scheduled in pg_cron, it
fails with syntax error ERROR: syntax error at or near "\" .
Since vacuum doesn't work inside a transaction block ERROR: VACUUM cannot
run inside a transaction block, I cannot use a function directly to run
over a loop.
Any guidance to make it work or an alternative?
