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.
