We can index multiple scalar values per row with GIN access method, and also can index single vector value per row with GiST AM.
Is it worth having a new AM to index multiple vector values per row? It will be an AM for the missing feature in below: | scalar | vector | ----------------+--------+--------+ single per row | btree | gist | multi per row | gin | *HERE* | We can call the new AM "gigist". Or, there might be another idea to support expression indexes for SRF functions, like =# CREATE TABLE tbl (c circle); =# CREATE INDEX ON tbl USING gist (unnest(c)); Comments and ideas welcome.
