I am having an issue with the size of a Postgres DB table.
The table have 17 columns. Out of them 5 jsonb columns. The table had 470000 rows when I checked from DBBeaver it showed the table size 34GB. After I deleted many rows from the table - it has currently 27038 rows. But the size of the table still shows 34GB.
I was expecting the size of the DB table to be reduced.
I event restarted the PG DB server service.
I am using Postgres v16 .
Can any body please advise, how to reduce the size of the table?
