feild seperator in awk script : I am trying to print columns in file which are seperated by "|" using awk.

File content :-

     postgres  | psql                   |               | 2018-09-17 
     05:00:45.096491+00 |            | active
     test_user | PostgreSQL JDBC Driver | ***.**.**.118 | 2018-09-17 
     03:55:22.310569+00 |            | idle in transaction
     test_user | PostgreSQL JDBC Driver | ***.**.**.95  | 2018-09-17 
     03:54:58.638521+00 |            | idle in transaction

I am using below awk command to seperate columns in file.

     awk 'BEGIN { RS = "|" } ; { print $2 }' vv.txt

Also refer to image attached which gives clear idea about issue.
I am not sure why datais getting messes up? Is it also considering space as separator[![enter image description here][1]][1].
