From: Tom Lane Date: Mon, 12 Nov 2018 16:50:28 +0000 (-0500) Subject: Simplify null-element handling in extension_config_remove(). X-Git-Tag: REL_12_BETA1~1256 X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=3de491482b6c815a2e735dbbb8972e0907d75188;p=postgresql Simplify null-element handling in extension_config_remove(). There's no point in asking deconstruct_array() for a null-flags array when we already checked the array has no nulls, and aren't going to examine the output anyhow. Not asking for this output should make the code marginally faster, and it's also more robust since if there somehow were nulls, deconstruct_array() would throw an error.
