formatting of SQL sent by PHP to postgres

Folks,
I have a question or two regarding PHP and Postgres on the issue of
speed:
1.    Is the semicolon at the end of SQL superflous when sent to Postgres?
Should it make much of a difference if I removed it?

2.    A lot of SQL issued have white space characters (newlines, tabs and
spaces) present - does this have any [major] impact on how quick
postgres gets to execute the SQL and return results?

k.
