Built-in Operator Classes

57.2. Built-in Operator Classes

The core PostgreSQL distribution includes the SP-GiST operator classes shown in Table 57-1.

Table 57-1. Built-in SP-GiST Operator Classes

名前Indexed Data TypeIndexable Operators
kd_point_opspoint << <@ <^ >> >^ ~=
quad_point_opspoint << <@ <^ >> >^ ~=
range_opsany range type && &< &> -|- << <@ = >> @>
text_opstext < <= = > >= ~<=~ ~<~ ~>=~ ~>~

Of the two operator classes for type point, quad_point_ops is the default. kd_point_ops supports the same operators but uses a different index data structure which may offer better performance in some applications.
