pgdump-tc — Total Commander plugins for PostgreSQL pg_dump custom dumps

Browse and read PostgreSQL custom-format dumps (pg_dump -Fc) directly inside Total Commander: schemas become folders, database objects (tables, views, sequences, functions, types, indexes, triggers …) become files, and tables open in an Excel-like data grid.

Works on PostgreSQL 11 … 17 dump archives (archive versions 1.13 … 1.16), including plain (gzip) archives and the optional eRGiss extensions (zstd compression, AES-256 encryption).

By Gabriel Diaconu — part of the eRGiss tooling suite. More open-source work: https://www.ergiss.ro/open-source.html

Screenshots

WCX — a dump as a folder tree (schemas = folders, objects = name.pg files, Size column = row count):

WLX — Excel-like data grid (press F3 on a .pg object; tabs Data / SQL / Info / Full SQL):

Two plugins

1. pgdump.wcx64 — packer plugin (WCX)

Open a .dump / .fc archive like a folder tree:

• schemas → folders, objects → name.pg files (read-only);
• a table's Size column shows its number of data rows;
• handles plain (gzip) archives and the eRGiss zstd/AES-256 variants (prompts for a password when the archive is encrypted);
• standalone — zlib, Zstandard and libgcrypt are linked into the DLL.

2. pgdump.wlx64 — lister plugin (WLX) — companion of the WCX

Press F3 on a name.pg object file:

• Tab 1 · Data — Excel-like grid with cell selection: arrows / Ctrl+arrows / Shift+arrows, Ctrl+C copies the selection as tab-separated text (paste into Excel). SQL NULL is shown as null.
• Tab 2 · SQL — the CREATE statement.
• Tab 3 · Info — dependent indexes / constraints / triggers / rules.
• Tab 4 · Full SQL — a complete reproducible script (CREATE + COPY data + indexes); Ctrl+C copies the whole thing — paste straight into psql.
• Esc closes the lister.

The WLX only makes sense together with the WCX (it views the .pg files the WCX extracts).

Install

Get them from the Total Commander Plugring:

• pgdump (WCX) — https://totalcmd.net/plugring/pgdump.html
• pgdump lister (WLX) — https://totalcmd.net/plugring/pgdump_lister.html

…or download the latest release here. Either way, open each plugin's zip in Total Commander and confirm the install prompt (the bundled pluginst.inf registers it automatically), or copy the .wcx64 / .wlx64 into a folder and add it under Configuration → Options → Plugins.

Read-only: these plugins never write to or modify your dump files.

Build (cross-compile on Linux with MinGW-w64)

# WCX (needs static zlib, zstd, libgcrypt, libgpg-error for the target):
bash build_wcx_pg.sh 64
# WLX (only system libraries):
x86_64-w64-mingw32-gcc -O2 -DWIN32 -D_WIN32_WINNT=0x0601 -I. -shared \
    wlx_pgdump.c pgdump_wlx.def -static -static-libgcc \
    -lcomctl32 -luser32 -lgdi32 -lkernel32 -o pgdump.wlx64

A portable reader library (pgfc_lib.c / pgfc.h) does all the archive parsing and can be reused on its own.
