Bitmap index
Started by Nonameabout 25 years ago2 messages
Hi,
on other RDBMS (Oracle,etc...),there is an index called bitmap index that
greatly improve performance compared to btree index for boolean value
(such as for a sex value,it's either M or F),i would like to know if such
index will be implemented inside PostgreSQL.
Best regards,
PEJAC Pascal

Yes, please do send in your implementation for review.
