I noticed that gram.y has NumericOnly: FCONST { $$ = makeFloat($1); } | '-' FCONST { $$ = makeFloat($2); doNegateFloat($$); } | SignedIconst { $$ = makeInteger($1); } ;
but SignedIconst: Iconst { $$ = $1; } | '+' Iconst { $$ = + $2; } | '-' Iconst { $$ = - $2; } ; The inconsistency here means that you can do, for example, regression=# set random_page_cost = +4; SET regression=# set random_page_cost = 4.2; SET but not regression=# set random_page_cost = +4.2; ERROR: syntax error at or near "4.2" LINE 1: set random_page_cost = +4.2; ^ That's weird enough in itself, and the problem is about to get more widespread because the partbound_datum production depends on NumericOnly. Any objections to allowing "+ FCONST" here? I'm inclined to fix this and back-patch it as well. regards, tom lane -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
