Hello All,
Need some help in scaling PostgreSQL:
I have a table with 400M records with 5 int columns having index only on 1
column.
Rows are updated by a perl script which takes 10k numbers in one transactions
and fires single single update in a loop on database keeping track of the

Then partition on the mobile number. If your updates and queries are all

Hello group,
is there a functionality like 'create or REPLACE table/view'
to circumvent drop with 'cascade' and recreation of depending objects?
I have a table schema1.x (col1, col2)
and a view schema1.v -> schema1.x(col1)
Another table is schema2.x(col1, col2) with same structure as x in schema
I firstly tried to "solve" the problem deleting the second parameter from all
the calls to the stringToQualifiedNameList function, I wouldn't expect it,
but it worked out, of course it was not the most elegant way.

Looks like pg_upgrade is using 32bit oids. 2147483647 is the max signed 32 bit
int, but the oids for my tables are clearly larger than that.

Hi,
I'm curious how do you handle results from multiple tables with
repeated column names. For example:
