Bash syntax error when attempting to check for database PID

Start with the divio project pull db [STAGE] command path and the database-server wait step that runs the shown docker exec ... psql command. Reproduce the failure using the listed local setup, then confirm that the database export completes without the Bash syntax error.

How to Reproduce

1. Go to your project's local directory.
2. Do divio project configure if there's no $PWD/.divio/config.json file. Otherwise, skip.
3. Ensure you have the docker-compose.yml file.
4. Run divio project pull db [STAGE] in a terminal.

Expectation vs. Reality

Reality: Bash syntax error just fired up.

Expectation: Database export ran smoothly.

There was an error trying to run a command. This is most likely
not an issue with divio-cli, but the called program itself.
Try checking the output of the command above.
The command was:
  docker exec 301e553875925ef50334bc5612c794eaebd2b00c8fae02f1e9c5373a998569dc psql -U postgres -c SELECT pg_terminate_backend(pg_stat_activity.pid) FROM   pg_stat_activity WHERE  pg_stat_activity.datname = 'db'   AND  pid <> pg_backend_pid();
