The first single quote after the left parenthesis is seen as ending
the function body, so postgres looks for the keyword LANGUAGE
immediately afterwards. Double your single quotes inside the function
body or backslash them:

CREATE FUNCTION testid()
RETURNS INTEGER
AS 'SELECT NEXTVAL(''seq1'');'
LANGUAGE 'SQL';

or

CREATE FUNCTION testid()
RETURNS INTEGER
AS 'SELECT NEXTVAL(\'seq1\');'
LANGUAGE 'SQL';
