I think we should first exhaust all options to use the currently supported formats, before adding a new controversial one. You can use the {s} qualifier for a box in ditaa and it'll show a disk; this ascii diagram produces a "similar enough" image to your diagram, for example:
+------------+ +---------+ | Original | pg_dump, other archive formats | Binary | | Database |------------------------------->| File(s) | | {s}| | {s} | +------------+ +---------+ | | | pg_dump, script format | pg_restore | | v v +------------+ +----------+ | SQL INSERT | psql | Restored | | commands |------------------------------>| Database | | {s} | | {s}| +------------+ +----------+ It takes more time to write this email than to get the diagram done. (I say "controversial" about inkscape because it was initially claimed that the output was going to be clean/readable/diffable, and that's what got so many upvotes. After the admission that that's not so, I suspect votes for inkscape have decreased somewhat.) -- Álvaro Herrera https://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services
