Postgres geometry column is always being altered to type geometry in every migration despite already being type geometry

Issue description

Postgres geometry column is always being altered to type geometry in every migration despite already being type geometry

Expected Behavior

A geometry column that is not modified should not be included in migrations

Actual Behavior

When performing a migration unrelated to a column that is of type geometry, every geometry column I have in my database is included in the migration.

For example:

await queryRunner.query(`ALTER TABLE "locations" ALTER COLUMN "coordinate" TYPE geometry`);

Steps to reproduce

1. Create an entity with a column of type geometry.

For example:

import {Point} from "geojson";

@Column("geometry")
coordinate!: Point

2. Create your database with the initial migrations

3. Alter another table in some way.

4. See that the migrations include modifying the entity with the geometry type.

For example:

await queryRunner.query(`ALTER TABLE "some_other_table" ALTER COLUMN "coordinate" TYPE geometry`);
