[postgis-users] Inserting column from another table

[Dylan Adams]

You'll need to use an UPDATE to accomplish what you're trying to do. It'll
probably look something like this

UPDATE Table1
SET geom = Table2.geom
FROM Table2
WHERE Table1.FabID = Table2.FabID;

There's more information in the Postgres' documentation about the UPDATE
statement:

http://www.postgresql.org/docs/9.4/interactive/sql-update.html
