I recently converted a load of GIST indexes used by tsearch2 to GIN, as my
app is read heavy. We now occasionally get the exception:
Query requires full scan, GIN doesn't support it
Thankfully it is happening very rarely, but as the querys are generated from
user input we can't stop this entirely.
Is this a permanent limitation of GIN, or is a fix possible?
Is a fix being worked on?
If a fix is forthcoming, will it be available in the 8.2 series or only 8.3+?
(It certainly looks like a bug to me, as the relevant queries work if the
index is dropped, and queries working or failing depending on the existence
of an index seems rather wrong to me.)
Only relevant discussion on this I can find is
appear to be no replies visible though :-(
