indexing - Best Postgresql index type to be used with not equal (<>) where condition -


i need query 2 identical huge tables (more milion records). besides other conditions, there not equal condition on columns pair of varchar type.

is standard btree type index suitable or other index type more suitable not equal (<>) condition?

why not try different indexes , let postgres tell effective explain command? unless data contains sort of rare edge case breaks indexing functionality, can test real , see actual results without having guess.
