From e2e2e15cf89ec67eeed443e4548b72e701a3d202 Mon Sep 17 00:00:00 2001 From: Tom Lane Date: Tue, 16 Aug 2005 00:48:43 +0000 Subject: [PATCH] Reject operator names >= NAMEDATALEN characters. These will not work anyway, and in assert-enabled builds you are likely to get an assertion failure. Backpatch as far as 7.3; 7.2 seems not to have the problem. --- src/backend/parser/scan.l | 11 ++++++++++- 1 file changed, 10 insertions(+), 1 deletion(-) diff --git a/src/backend/parser/scan.l b/src/backend/parser/scan.l index c3a423a7f4a..c87752fc5e4 100644 --- a/src/backend/parser/scan.l +++ b/src/backend/parser/scan.l @@ -9,7 +9,7 @@ * * * IDENTIFICATION - * $Header: /cvsroot/pgsql/src/backend/parser/scan.l,v 1.111.2.1 2004/02/21 00:35:13 tgl Exp $ + * $Header: /cvsroot/pgsql/src/backend/parser/scan.l,v 1.111.2.2 2005/08/16 00:48:43 tgl Exp $ * *------------------------------------------------------------------------- */ @@ -479,6 +479,15 @@ other . return yytext[0]; } + /* + * Complain if operator is too long.
