OK, so we have code in the backend to force a toast table in the new
cluster if there isn't one in the old cluster, e.g.:
/* * Check to see whether the table actually needs a TOAST table. * * If an update-in-place toast
relfilenodeis specified, force toast file * creation even if it seems not to need one. */ if
(!needs_toast_table(rel)&& (!IsBinaryUpgrade || !OidIsValid(binary_upgrade_next_toast_pg_class_oid)))
return false;
What we never considered is case where the old cluster didn't have one
and the new one does.
What I would like you to do is to use the 9.3 pg_dump and create a
schema-only dump:
pg_dump --schema-only --binary-upgrade
Find the table that is getting the toast file on the new cluster but not
the old one, and run all the commands related to that table from the
dump --- you don't need to load any data, just the schema items.
Run that on the old cluster and the new cluster, then check if you are
getting the same case where there is no toast table on the old cluster
but one on the new cluster. Remember to only use the 9.3 pg_dump output
for both old and new clusters.
Thanks.
