+Many suggestions from the puppet forums to run query shown below, didn't helped.
+<code bash | depend on your puppet version select one which works>
+sudo -u postgres psql puppetdb -c 'delete from catalogs where certname in (select certname from certnames where certname like '%testserver.k2patel.in%');'
+sudo -u postgres psql puppetdb -c 'delete from catalogs where id in (select id from certnames where certname like '%testserver.k2patel.in%');'

+Only thing worked for me to drop database and recreate.
+<code bash>
+systemctl stop puppetdb
+su - postgres
+dropdb puppetdb
+createdb -E UTF8 -O puppetdb puppetdb
+psql puppetdb -c 'create extension pg_trgm';

+=== Mapping values ===

+<%- $ips = $vs_map[$name].map |$val| { $val['address']['ip'] } -%>
