Hi:
I'm working on a project where I need to know how Postgresql determines which "Access Plan" to use when executing specific Select-SQL sentences; whether Postgresql decides to use a specific Index or not and how Postgresql determines if the index has to be used; and how Postgresql parsers a Select-SQL sentence depending on the order of the WHERE clauses.
Where can I find specific information about this?.
Thank you very much for your help.
