Your requirements are several.
To get anywhere, we need to know/see a lot of things:
first: what db?
second: a sample of the input file with an alter table line
third: your expected output from that input file - I guess a table name
fourth: how do you propose to determine the fields you need to add?

psfxtable
PSFXTABLE(1) General Commands Manual PSFXTABLE(1)
NAME
psfxtable - handle Unicode character tables for console fonts
SYNOPSIS
psfxtable [-i infont] [-o outfont] [-it intable] [-ot outtable] [-nt]
DESCRIPTION
psfxtable handles the embedded Unicode character table for .psf format console fonts. It reads a font and possibly a table and writes a
font and/or a table. psfaddtable(1), psfgettable(1) and psfstriptable(1) are links to it.
Each of the filenames infont, outfont, intable, and outtable may be replaced by a single dash (-), in which case standard input or standard
output is used. If no -i option is given, the font is read from standard input. If no -it or -o or -ot option is given, no input table is
read or no output font or output table is written.
By default the output font (if any) will have a Unicode table when either the input font has one, or an explicit table (which overrides an
input font table) has been provided. The option -nt causes output of a font without table. When outfont is requested it will get a psf1
header when infont has a psf1 header and intable does not have sequences and a psf2 header otherwise.
