Hi Team,

Getting below error while creating extension.

postgres=#  CREATE EXTENSION plperl;
LOG:  disconnection: session time: 0:00:06.662 user=postgres
database=postgres host=10.228.13.46 port=42106
server closed the connection unexpectedly
        This probably means the server terminated abnormally
        before or while processing the request.
The connection to the server was lost. Attempting reset: Succeeded.
