pg-dump-filter

==============

`pg-dump-filter` is a tool that filters tables from a regular

PostgreSQL dump file. It could be used to reload some tables from a

dump in living instance, or to ignore others while creating a test

environment.

Install

-------

This tool is written in [Rust language](https://www.rust-lang.org/). 

Install it, then run:

  cargo install

Usage

-----

    Usage: pg-dump-filter [options]

    Options:

        -t, --table NAME    output only tables matching NAME

        -T, --exclude-table NAME

                            no not output tables matching NAME

        -c, --copy-only     output only COPY FROM statements

        -r, --truncate      empty tables before COPY FROM statements

        -h, --help          print this help menu

Examples

--------

To reload *pool* and *customer* tables datas to an existing database :

    pg-dump-filter -cr -t "pool|customer" < dump.sql | psql mydatabase

    

To load a complete dump excluding *log* datas :

    pg-dump-filter -T log < dump.sql | psql mydatabase

Important notice

----------------

Tables arguments folows the [regex rust library

syntax](https://docs.rs/regex/0.2.2/regex/#syntax). For example the

argument:

    -t "pool|customer"

matches all `*pool*` and `*customer*` table names. If you want an

exact match, you have to type:

    -t "^pool$|^customer$"`

    

Be warned.

I've written this tool for personal needs. If you find it useful,

don't hesitate to send me some remarks for improvements requests.
