Add generic zodb-convert support for all storage backends#38
Merged
Conversation
Generate storage-agnostic convert-import.conf and convert-export.conf for all non-filestorage backends (RelStorage, PGJsonb, ZEO) using the generic zodb-convert tool. Filestorage is always the portable format on the other side of the conversion. - Add tagmarker parameter to pgjsonb() and zeo() macros in db.conf - Add db_convert_import/export_* settings to cookiecutter.json - Create convert-import.conf and convert-export.conf templates - Update post_gen_project.py for directory creation and file cleanup - Deprecate RelStorage-specific zodbconvert configs in favor of zodb-convert - Add migration how-to guide (docs/sources/how-to/migrate-storage.md) - Update storage-backends explanation and backend how-to guides - Keep existing relstorage-import/export.conf for backward compatibility Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
