Re: Major upgrade advice

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Just to mention one issue we had here:

In 8.1 we did this to retrieve all data from a specific date:
SELECT * FROM xxx
WHERE <timestamp_column> LIKE '2008-05-20%'

In 8.3 we had to change to:
SELECT * FROM xxx
WHERE <timestamp_column> >= CAST('2008-05-20' as timestamp) AND
     <timestamp_column> < CAST('2008-05-21' as timestamp)

I'm getting ready to tackle another upgrade: 7.4.6 -> 8.3.3. The preliminaries (development/testing) look good but I'd like suggestions/warnings/comments on:

1. Removing OIDs on user tables.

I don't see any dump or restore options to remove OIDs. Am I better off modifying the dump to alter the "SET default_with_oids = true;" lines or going through all the user tables in advance and running "ALTER TABLE ... SET WITHOUT OIDS"? Other options?

2. Alter encoding from C to utf8.

Cheers,
Steve
