I need to use the value of an environment variable as part of an SQL
query within psql.

I can do the following withing psql:

\set local_site `echo $FXA_LOCAL_SITE

\echo local site = :local_site

The result is "local_site = xxx" which is correct.

What I really want to do is the following:

\set local_site `echo $FXA_LOCAL_SITE

UPDATE table_name SET office_id = :local_site;

This results in the message

column "xxx" does not exist

Is there any way that I can use the value of the FXA_LOCAL_SITE env
variable in my UPDATE statement?
