I would like to know if there are any oracle equivalent of dbms_mview.estimate_mview_size in Postgres as we have been using it in Oracle for estimating required size for the upcoming mviews but after migration to Postgres we find it very hard to estimate the size.. Sometime our rds ran out of space and we had to spend lot of efforts and time to bring back the rds once after rds storage is exhausted.
Or is there any other options available which can be used to estimate the size.
