Doh! Can you please send another patch with gram.y as well. Mine is
missing all of the thick index stuff.
I apologize for the mistake. I am sending the revised patch - generated against CVS Head. Thanks for the guidance provided.
This patch also fixes a bug, which appeared in select count(1) from table where varchar_column like 'xx%' kind of queries.
In order to find out whether the index will be able to answer all the where clause conditions, i have put the checks under expand_indexqual_conditions function. Please get back, if there is any problem with the approach.
Waiting for feedback...
Thanks,
Gokul.
