Question

PostgreSQL

Some problems with Query time

bash-4.2$ psql -qtAX -h "$1" -p "$2" -U "$3" -d "$4" -v tmax=$5 -f "/var/lib/zabbix/postgresql/pgsql.query.time.sql"
psql:/var/lib/zabbix/postgresql/pgsql.query.time.sql:31: ERROR:  syntax error at or near ")"
СТРОКА 22: ...'epoch' FROM (clock_timestamp() - query_start)) > )::integer...

I don't understand the error in the request itself, tell me what the problem is please
