Subject: Reset error message at PQreset()
X-Git-Tag: REL9_1_15~82
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=8f7bd8e91da321cb38f09087a4b9411277917b13;p=postgresql

Reset error message at PQreset()

If you call PQreset() repeatedly, and the connection cannot be
re-established, the error messages from the failed connection attempts
kept accumulating in the error string.

Fixes bug #11455 reported by Caleb Epstein. Backpatch to all supported
versions.
