    Details

      Description

      PosgreSQL DB crashes when using Debezium (tested with both indicated versions) Embedded Engine and a PostGIS geometry is inserted.

      A test project documenting all the steps to reproduce it has been created here: https://github.com/fmiguelez/dbztest

      Please read README.md to follow the steps to reproduce it.

      • An application using debezium-embedded and debezium-connector-postgres connects to PostgreSQL DB with PostGIS extension.
      • An INSERT is issued with a geometry
      • Both PosgreSQL and Application crash

      PosgreSQL crash output:
