Everybody who uses psql uses less pager. It is working well, but there is not any special support for tabular data. I found few projects, but no one was completed for this purpose. I decided to write some small specialized pager for usage as psql pager.

This pager can be used from mysql and pgcli clients too.

• possibility to freeze first few rows, first few columns
• possibility to use fancy colors - like mcview or FoxPro

• -b black/white theme
• -X doesn't clean screen on the end
• -s N use theme (default theme is mc theme)
• -c N freeze first N columns
• -f file open file (default stdin)
• --force-uniborder replace ascii border by unicode borders
• -g --hilite-search don't highlight lines for searches
• -G --HILITE-SEARCH don't highlight lines for searches ever
• --help show this help
• -i --ignore-case ignore case in searches that do not contain uppercase
• -I --IGNORE-CASE ignore case in all searches
• --less-status-bar status bar like less pager
• --no-mouse without own mouse handling (cannot be changed in app)
• --no-sound without sound effect
• -F, --quit-if-one-screen quit if content is one screen
• -V, --version show version

\pset linestyle unicode
\pset border 2

some possible configuration:

-- Switch pagers with :x and :xx commands
\set x '\\setenv PAGER less'
\set xx '\\setenv PAGER \'pspg -bX --no-mouse\''
:xx

MariaDB [sakila]> pager pspg -s 14 -X --force-uniborder --quit-if-one-screen
PAGER set to 'pspg -s 14 -X --force-uniborder --quit-if-one-screen'
MariaDB [sakila]> select now();
MariaDB [sakila]> select * from nicer_but_slower_film_list limit 100;

LC_CTYPE should be correct.

Some linker issues can be fixed by:

I changed 
gcc -lncursesw pager.c -o pspg -ggdb
to
gcc pager.c -o pspg -ggdb -lncursesw

On some old systems a compilation fails with error

/home/user/Src/pspg-0.6/src/pspg.c:2403: undefined reference to `set_escdelay'

In this case comment line with function set_escdelay

The pspg is available from community repository https://yum.postgresql.org/packages.php

# emerge -av dev-db/pspg

# pkg install pspg

# port install pspg
