5. this gives the following trace:

   Caused by: org.nuxeo.ecm.core.api.NuxeoException: Could not insert: INSERT INTO "image_metadata" ("id", "color_space", "user_comment", "image_description", "date_time_original", "focal_length", "white_balance", "copyright", "fnumber", "pixel_xdimension", "equipment", "orientation", "exposure_time", "xresolution", "iso_speed_ratings", "icc_profile", "yresolution", "pixel_ydimension", "focallength") VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)

6. the issue is specific to PgSQL and does not happen with embedded H2 or OracleDB

The problem is that 0x00 characters are embedded in the comment field, and writing a text field with 0x00 characters is forbidden on PostgreSQL.
