This might be more of a bash question, or it might be a psql vs engine problem.
I want to run this query using psql from a bash prompt: select format('SELECT ''%s'', MIN(part_date) FROM %s;', table_name, table_name) from dba.table_structure order by table_name\gexec
Thus, I added an extra back
$ psql sides -atXc "select format('SELECT ''%s'', MIN(part_date) FROM %s;', table_name, table_name) from dba.table_structure order by table_name limit 5\\gexec" select format('SELECT ''%s'', MIN(part_date) FROM %s;', table_name, table_name) from dba.table_structure order by table_name limit 5\gexec ERROR: syntax error at or near "\" LINE 1: ...) from dba.table_structure order by table_name limit 5\gexec
Removing "\\exec" from the statement, and appending -c "\\gexec" to the psql command technically worked, but did not run the commands.
I don't know why, but \g* commands don't work from the -c option. But in this case it is not necessary
