  Terminal/console execution
    Usage: pg_format [options] file.sql [...]

            PostgreSQL SQL queries and PL/PGSQL code beautifier.


        file.sql can be a file or use - to send a query using stdin. Use a single
        dot in a line to terminate the stdin input or EOF.

        Returning the SQL formatted to stdout or into a file specified with the
        -o | --output option.


        -a | --anonymize      : obscure all literals in queries, useful to hide
                                confidential data before formatting.
        -d | --debug          : enable debug mode. Disabled by default.
        -f | --function-case N: Change the case of the reserved keyword. Default is
                                unchanged: 0. Values: 0=>unchanged, 1=>lowercase,
                                2=>uppercase, 3=>capitalize.
        -h | --help           : show this message and exit.
        -m | --maxlength SIZE : maximum length of a query, it will be cut above
                                the given size. Default: no truncate.
        -n | --nocomment      : remove any comment from SQL code.
        -o | --output file    : define the filename for the output. Default: stdout.
        -s | --spaces size    : change space indent, default 4 spaces.
        -u | --keyword-case N : Change the case of the reserved keyword. Default is
                                uppercase: 2. Values: 0=>unchanged, 1=>lowercase,
                                2=>uppercase, 3=>capitalize.
        -v | --version        : show pg_format version and exit.


        cat samples/ex1.sql | /usr/local/bin/pg_format -
        /usr/local/bin/pg_format -n samples/ex1.sql
        /usr/local/bin/pg_format -f 2 -n samples/ex1.sql -o result.sql

  CGI context
    Install pg_format into your cgi-bin folder, grant execution on it as a
    CGI script (maybe you should add the .cgi extension) and get it from
    your favorite browser.

    You have a live example without limitation than ten thousand characters
    in your SQL query here:


    pg_format will automatically detected that it is running in a CGI
    environment and will output all html code needed to run an online code
    formatter site. There's nothing more to do.

    Download the tarball from github and unpack the archive as follow:

            tar xzf pgFormatter-x.x.tar.gz
            cd pgFormatter-x.x/
            perl Makefile.PL
            make && sudo make install

    This will copy the Perl script pg_format in /usr/local/bin/pg_format
    directory by default and the man page into
    /usr/local/share/man/man1/pg_format.1. Those are the default
    installation directory for 'site' install.

    If you want to install all under /usr/ location, use INSTALLDIRS='perl'
    as argument of Makefile.PL. The script will be installed into
    /usr/bin/pg_format and the manpage into /usr/share/man/man1/pg_format.1.

    For example, to install everything just like Debian does, proceed as

            perl Makefile.PL INSTALLDIRS=vendor

    By default INSTALLDIRS is set to site.

    With pgFormat, you can just add the following line to your ~/.vimrc

            au FileType sql setl formatprg=/usr/local/bin/pg_format\ -

    This lets your gq commands use pgFormat automagically. For example if
    you are on the first line, typing:


    will format the entire file.


    will format the next two line.
