A modernized, interactive TUI alternative to pg_waldump for exploring PostgreSQL Write-Ahead Logs.

• Visual Transaction Tracking: Visually track COMMITs and ABORTs with colored, dynamically drawn graph lines.
• Deep Drill-down: Detail split view. Inspect XLogRecord details, block-level information (RelFileNode), and Full Page Images (FPI) instantly.

git clone https://github.com/MasahikoSawada/pg_walview.git
cd pg_walview

# Standard build (relies on `pg_config` in your PATH)
cargo build --release

# If you have a custom PostgreSQL installation, specify the include path:
PG_INCLUDE_DIR=/path/to/pgsql/include/server cargo build --release

Note that pg_walview currently supports only PostgreSQL 18.

Simply pass the path to a PostgreSQL WAL file as an argument:

pg_walview /path/to/pg_wal/000000010000000000000001
