Type-specific additional information, for example the max length for
a CHARACTER(n) column or the precision for a TIMESTAMP(n) column.
This is poorly documented, but you can figure out the encoding by
experimentation --- there are only a very small number of types that use
typmod, since by definition special type declaration syntax is needed
for each such type.
