I have a set of tables that periodically need to be thrown away and
completely rebuilt with new data. I'm using JDBC to interact with
PostgreSQL.
Is there a straightforward and efficient way to do this?
I tried using the commit/rollback methods in JDBC but blew Java memory out
of the water (these are decent-sized but not enormous datasets: 60,000
records more or less).
I investigated using 'alter table ... rename to ...' but it didn't seem to
also rename the associated indexes, and before actually implementing code to
do it I want to ask if that would actually work. (If it did it would be the
best way to go, as I have plenty of disk space available for an extra temp
copy of the database).
The tables are very simple, with primary keys and in one case a supplemental
additional index.
Any advice would be appreciated.
