We have a PostgreSQL table with about 400000 records in it. Using either RODBC or RdbiPgSQL, what is the fastest way to update one (or a few) column(s) in a large collection of records? Currently we're sending sql like
BEGIN UPDATE table SET col1=value WHERE id=id (repeated thousands of times for different ids) COMMIT and this takes hours to complete. Surely there must be a quicker way?
