I've tried searching the documentation to answer this question but could
not find anything. When trying to choose the optimal fillfactor for an
index, what is important the number of times the row is updated or the
column indexed upon is updated? In my case each row is updated on
average about
Thank you! setting the protocolVersion=2 works with the newer driver.
I'm still puzzled as to why the prepareThreshold=0 doesn't force the
replan though.

Thanks for the suggestion. Actually I went ahead and created a reverse
function using plpgsql, created an index using reverse column and now
my queries use "where reverse(column) like reverse('%2345') and it's
using the index like i hoped it would! Now if I could figure out how
to optimize like '
Is there any way to create a reverse index on string columns so that
queries of the form:
where column like '%2345';

Is the only way to create a reverse function and create an index using
the reverse function and modify querie
