## Assume that .port is port number and .dbname is the database name
cid1 <- db.connect(port = .port, dbname = .dbname, verbose = FALSE)
cid2 <- db.connect(port = .port, dbname = .dbname, verbose = FALSE)

db.list() # list the above two connections

conn.eql(cid1, cid2) # returns TRUE

db.disconnect(cid1, verbose = FALSE)
db.disconnect(cid2, verbose = FALSE)
