Split a postgresql script file into statements
pgsplit takes a PostgreSQL format sql script on stdin, and spits it out
on stdout with each statement separated by a zero byte.
This is for database migration code that wants to send each statement to the database separately, rather than sending the entire script as a giant semicolon separated string.
It could probably be abused along with xargs -0 to do something interesting
too.
It's very simple. It splits the file at each line that ends with a semicolon that isn't inside a quoted string.
Strings quoted with single quotes or dollar-quoting.
Nested quotes.
