Partitioning an existing table - Mailing list pgsql-general

Hi.

The partitioning documentation in PG is very clear on how to partition
a new table. Create child tables, and have triggers that manage
INSERT, UPDATE and DELETE commands.

How about doing this with existing massive tables? (Over 120 million rows)

I could create a new parent table with child tables, and then INSERT
all these millions of rows to put them into the right partition. But
is that recommended?

Thanks
