无法使用sqlx库golang触发\ copy命令

Question

I am unable to fire the the below Exec command using golang sql library

db.Exec("\\COPY schema.table TO './tablename.csv' DELIMITER ',' NULL as 'null' CSV HEADER ;") I get exception syntax error at or near ""\COPY

If I use as below db.Exec("\COPY schema.table TO './tablename.csv' DELIMITER ',' NULL as 'null' CSV HEADER ;")

I get error like syntax error at or near "\"

I cannot fire COPY TO as command as I should be super user pq: must be superuser to COPY to or from a file

Anyway to fire the \copy to command using sql library?

I am able to run this command successfully from shell prompt using psql
