Subject: Implement PREPARE AS statement for ECPG.
X-Git-Tag: REL_12_BETA2~134
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=a1dc6ab465986a62b308dd1bb8da316b5ed9685a;p=postgresql

Implement PREPARE AS statement for ECPG.

Besides implementing the new statement this change fix some issues with the
parsing of PREPARE and EXECUTE statements. The different forms of these
statements are now all handled in a ujnified way.
