Functions ¶
func Split ¶
Use bufio.Scanner to split a PostgreSQL string into multiple statements.
The core problem is to figure out whether the current ; separator is inside an escaped string literal. PostgreSQL has multiple ways of opening a string literal, $$, ', --, /*, etc. We use a FSM to guarantee these states are entered exclusively. If not in one of the above escape states, the next ; token can be parsed as statement separator.
Each statement is split as it is, without removing comments or white spaces.
