I think there is a problem with the PostGIS-writer and the new PostgreSQL version 10. In PostgreSQL 9.6 there were no problems. Since I installed the version 10 of PostgreSQL (with PostGIS 2.4.1) the following error is thrown:
Error executing SQL command ('SELECT AddGeometryColumn('test', 'myTableName', 'geom', 3034, 'GEOMETRY', 2)'): 'ERROR: Schema 'test' is not a valid schemaname
"test" is not the schema name, it is the database name. The schema isn't recognized in this command.
