In commit 0ac5ad5134 I changed some error messages from "FOR UPDATE/SHARE" to a rather long gobbledygook which nobody liked. Then, in commit cb9b66d31 I changed them again, but the alternative chosen there was deemed suboptimal by Peter Eisentraut, who in message 1373937980.20441.8.camel@vanquo.pezone.net proposed an alternative involving a dynamically-constructed string based on the actual locking strength specified in the SQL command. This patch implements that suggestion.
