Postgresql, sum of float turns into int

[Jcambass]

Version

1.29.0

What happened?

The generated code uses an int64 despite the database column being a FLOAT.

Changing the engine to sqlite generates the correct code.

I suspected that sqlc detects the wrong postgres type in the first place since changing the query to SELECT CAST(SUM(length) as FLOAT) FROM foo; makes it work as expected.

Relevant log output

Database schema

CREATE TABLE foo (
  length FLOAT NOT NULL
);

SQL queries

-- name: Total :one
SELECT SUM(length) FROM foo;

Configuration

{
  "version": "2",
  "sql": [{
    "schema": "schema.sql",
    "queries": "query.sql",
    "engine": "postgresql",
    "gen": {
      "go": {
        "out": "db"
      }
    }
  }]
}
