Hello, is there any way to find if there are any dblink exist on the 9.6
postgresql server?
Are looking for whether the extension was installed?
If so then in psql:
\dx
will tell you.
Or are you looking for code that uses dblink?
AFAIK dblink creates connections on demand not from information in a
persistent store. So there is no table you can query to get the
information. You would have to search your code(internal and external)
for references to it.
If there are open connections you can use:
https://www.postgresql.org/docs/11/contrib-dblink-get-connections.html
dblink_get_connections — returns the names of all open named dblink
connections
