Is there an option in PostGIS (in query or table option) to set the return type of a Geometry?

I'm using this query:

select * from "locations" where "locations"."id" = 2 limit 1

And that will return

2;"My Home";"My Address";"0101000020E6100000EC14AB0661855EC010CF126404B64240"

But I want to default return the geometry as JSON, without naming the parameters, I mean, I don't want to do:

select id, name, address, ST_AsGeoJSON (location) from "locations" where "locations"."id" = 2 limit 1

I just want to continue using select * and returning location as GeoJSON by default. Is this possible?

    Create a view and select * it.

  • I think your title is a ambiguous. When I read "type of geometry", my thought goes to "Point", "Linestring" etc. etc. I'd suggest the term "geometry representation" or "geometry format" instead.

  1. Create a view

    CREATE VIEW v_location AS SELECT id, name, address, ST_AsGeoJSON (location) AS location FROM "locations";

  2. Use the "SELECT *" on it:

    SELECT * FROM v_location where "locations"."id" = 2 limit 1
