B-tree operator family containing 1 classes, 5 operator strategies and 3 support functions in this source build.

Family operator strategies

Operator overload	Strategy	Purpose	Membership scope	Source description
<(timetz,timetz)	1	search	Family member	less than
<=(timetz,timetz)	2	search	Family member	less than or equal
=(timetz,timetz)	3	search	Family member	equal
>=(timetz,timetz)	4	search	Family member	greater than or equal
>(timetz,timetz)	5	search	Family member	greater than

Family support functions

Support number	Left type	Right type	Function signature	Result type
1	timetz	timetz	timetz_cmp(timetz,timetz)	int4
4	timetz	timetz	btequalimage(oid)	bool
3	timetz	interval	in_range(timetz,timetz,interval,bool,bool)	bool
