multiple sql results to shell

I have this bash/sql script which outputs some curl commands. the
backticks causes it to get interpreted by the shell. This works fine if
there is one result, but when there are many rows returned, it looks like
one shell command.

any help on getting multiple rows returned to be executed by the shell
would be appreciated!

thanks!

`psql -P "tuples_only=on" -h ${DB_HOST} -d ${DB_NAME} -U ${DB_USER} -c
"select 'curl -X POST http://${REGISTER_HOST}:8080/' || source_id ||
'/${MT}/' || model || '/' || site || '/backoffice/register' from
myschema.events where source_id = $SOURCE_ID and ineffective_date is null"`
