Browse a "pg_dump -Fc" archive as a tree: schemas as folders, objects as .sql files; view/copyout yields a runnable SQL script (CREATE + COPY data + dependent indexes/constraints/triggers). Pure Python, stdlib only (gzip); zstd via the optional "zstandard" module. Handles archive versions 1.12..1.16 (PostgreSQL 9.x..17). Registered in mc.ext.ini by content type.

extfs: pgdump helper for PostgreSQL pg_dump custom-format archives
A read-only extfs helper that lets you browse a
pg_dump -Fcarchive inside mc as a folder tree:.sqlfiles;CREATEstatement, its data as aCOPYblock (terminated with\.), and the dependent indexes / constraints / triggers, so it pastes straight intopsql.Implementation notes:
zlib); Zstandard-compressed archives (PostgreSQL 16+) are read when thezstandardmodule is installed;tableamsince PG12,relkindsince PG17, and the 1.15 one-byte compression-algorithm header);mc.ext.iniby content type (PostgreSQL custom database dump) so it triggers for any file extension.Tested against dumps produced by PostgreSQL 11 and 17 (plain and gzip).
