I have a table with 15 cols , there is an joint index on 5 of them
there are ~15million records in the table, and it gets heavy use via
update & insert
i recently noticed that after a day of use, the index is no longer
being respected in some/all queries and a seq scan on the table is used
i ran analyze, no change.
i ran vacuum analyze, no change.
i dropped the index, and recreated it -- its now used again.
this happened 3x already this week.
can anyone offer a suggestion?
