Hello,I use multi-schemas in one database in Postgres,such as
```
Postgres(instance)
MyDB
public
MySchema1
table1
table2
MySchema2
table1
table2
MySchema3
table1
table2
```
And It's open to my users,my users will run queries,
such as
User1:
```
set search_path=MySchema1;
select * from table1,table2;
```
User2:
```
set search_path=MySchema2;
select * from table1,table2;
```
User3:
```
set search_path=MySchema3;
insert into table3 select * from MySchema1.table1,MySchema2.table2;
select * from table3;
```
I want to show current schema of running queries,But pg_stat_activity can only show database name, not schema name.
I want current schema (search_path ) as
| datname | username | schema | query |
| -------- | -------- | -------- | -------- |
| MyDB | User1 | MySchema1 | select * from table1,table2; |
| MyDB | User2 | MySchema2 | select * from table1,table2; |
| MyDB | User3 | MySchema3 | insert into table3 select * from MySchema1.table1,MySchema2.table2; |
Is there any sys views can do it?
no, there is nothing for this purpose.
you can use application_name
so user can do
SET search_path=MySchema;
SET application_name = 'MySchema';
SELECT * FROM ...
Thank you!
Best regards,
CavonChen
