I'd like to do the following for large frequent updates on central
table with ~1m rows:
1. Create new table like original
2. Populate new table
3. DROP original table
4. RENAME new table to original
Some testing revealed that in pg 8.4 and 9.1, if another session
queries the table between 3 and 4, the query fails with error 'could
not open relation with OID nnn.' In pg 9.3 there's no error.

This seems to be the topic of conversation here:
<http://www.postgresql.org/message-id/flat/12791(dot)1310599941(at)sss(dot)pgh(dot)pa(dot)us#12791(dot)1310599941@sss.pgh.pa.us>
<http://www.postgresql.org/message-id/flat/20285(dot)1340769074(at)sss(dot)pgh(dot)pa(dot)us#20285(dot)1340769074@sss.pgh.pa.us>
Do I correctly infer that the change in behavior was an intentional
fix and that with pg >= 9.3 I can rely on the above method working
without any risk of this error in my queries?
Much appreciated,
