PL/pgSQL doc sample bug? (in 7.1.3)

Hello,

I could not execute sample code of plsql.sgml. PostgreSQL version is 7.1.3.
Then I made patches for reference.

1) cs_refresh_one_mv function sample code bug. *** 512,526 ****
2) Singule quotation missing. *** 1152,1158 ****
3) cs_refresh_mviews function sample code bug. *** 1305,1313 ****

Please review my patch.
Thank you.

Following plsqlORG.sgml file is a current CVS file.
