[patch] Typo in ECPG Docs

Hi,

I just stumbled across a spurious indefinite article in the ECPG docs.
See the attached patch.

Speaking of indefinite articles, there seems to be some inconsistency
in using "a SQL ..." and "an SQL ..." throughout the docs. This could
probably be easily fixed using a script, but I'm not sure if I'm
missing some grammatical details here, since English isn't my native
language.

regards,
Andreas
