This repository contains implementations for the Multi-Entry GiST and SP-GiST access methods. These access methods are variations of the GiST and SP-GiST indices, allowing for more efficient indexing of complex and composite data types.

The repository contains 3 PostgreSQL extensions split into 3 separate folders:

• mest:
  • contains the Multi-Entry GiST access method and an implementation of a multi-entry R-tree for the PostgreSQL multirange and path types.
  • contains the Multi-Entry SP-GiST access method and an implementation of a multi-entry Quadtree for the PostgreSQL multirange and path types.
• postgis-mest:
  • contains the implementation of a multi-entry R-tree, multi-entry Quadtree, and multi-entry Kd-tree for the PostGIS geometry and geography types.
• mobilitydb-mest:
  • contains the implementation of a multi-entry R-tree, multi-entry Quadtree, and multi-entry Kd-tree for the MobilityDB spanset and tgeompoint types.

For more information about each extension, please refer to their associated README file.

• PostgreSQL 17

Compiling and installing the mest extension

make PG_CONFIG=path_to_postgresql_installation/bin/pg_config
sudo make PG_CONFIG=path_to_postgresql_installation/bin/pg_config install

You may omit the PG_CONFIG overrides if running pg_config in your shell locates the correct PostgreSQL installation.
