Dollar-quoted PostgreSQL function definitions are parsed incorrectly in some situations

[arlampin]

What version of Flyway are you using?

4.0

What database are you using (type & version)?

PostgreSQL 9.5 and 9.4

What operating system are you using?

Linux

What did you do?

Using the following SQL

CREATE TABLE sometable1 (
  id        SERIAL PRIMARY KEY,
  somefield TEXT CHECK (somefield ~ E'.')
);

CREATE OR REPLACE FUNCTION testfun1()
  RETURNS TEXT AS $$
BEGIN
  RETURN E'foo';
END;
$$ LANGUAGE 'plpgsql';

fails with

  Migration V1__Test.sql failed
  -----------------------------
  SQL State  : 42601
  Error Code : 0
  Message    : ERROR: unterminated dollar-quoted string at or near "$$
  BEGIN
    RETURN E'foo'"
    Position: 59
  Location   : src/main/resources/migrations/V1__Test.sql 
  Line       : 1

but

CREATE TABLE sometable1 (
  id        SERIAL PRIMARY KEY,
  somefield TEXT CHECK (somefield ~ E'.')
);

CREATE TABLE sometable2 (
  id        SERIAL PRIMARY KEY,
  somefield TEXT CHECK (somefield ~ E'.')
);

CREATE OR REPLACE FUNCTION testfun1()
  RETURNS TEXT AS $$
BEGIN
  RETURN E'foo';
END;
$$ LANGUAGE 'plpgsql';

doesn't, and neither does a version without escaped (E'') strings or a version with just the function definition alone.

Applying the migration directly with psql works.

Thanks! Fixed.
