      1) Install postgres (any version) using either wal2json or pgoutput (untested with decoderbufs)

      2) Create a table with a column of type "timestamp without time zone"

      3) Turn on debezium and listen to changes to that table

      4) Insert a record with a timestamp value of "-infinity"

      5) Debezium crashes as its unable to parse "-infinity"
