Syntax problem with cron wal-g command

[garry-t]

Fix syntax issue inside cron file #657
Plus fix problem with wal-g run, config file now specified in command directly.

This is a simplest solution I found. Minimum changes required, but now it works

@garry-t why not simplify the check for the same as for pgbackrest?

if [ $(psql -tAXc 'select pg_is_in_recovery()') = 'f' ]; then wal-g backup-push {{ postgresql_data_dir }} > {{ postgresql_log_dir }}/walg_backup.log 2>&1; fi

or

[ $(psql -tAXc 'select pg_is_in_recovery()') = 'f' ] && wal-g backup-push {{ postgresql_data_dir }} > {{ postgresql_log_dir }}/walg_backup.log 2>&1

I don't see the need for different approaches.

I kept solution closer to original. Will check your suggestion.
