From 7ef5ccffcb7bc71d298427e7b2c3a2cfae8556c6 Mon Sep 17 00:00:00 2001 From: Euler Taveira Date: Wed, 24 Jan 2018 17:01:31 -0200 Subject: [PATCH 4/8] Rename a WHERE node A WHERE clause will be used for row filtering in logical replication. We already have a similar node: 'WHERE (condition here)'. Let's rename the node to a generic name and use it for row filtering too. --- src/backend/parser/gram.y | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) diff --git a/src/backend/parser/gram.y b/src/backend/parser/gram.y index 3dc0e8a4fb..61cc59fe7c 100644 --- a/src/backend/parser/gram.y +++ b/src/backend/parser/gram.y @@ -476,7 +476,7 @@ static Node *makeRecursiveViewSelect(char *relname, List *aliases, Node *query); %type def_arg columnElem where_clause where_or_current_clause a_expr b_expr c_expr AexprConst indirection_el opt_slice_bound columnref in_expr having_clause func_table xmltable array_expr - ExclusionWhereClause operator_def_arg + OptWhereClause operator_def_arg %type rowsfrom_item rowsfrom_list opt_col_def_list %type opt_ordinality %type ExclusionConstraintList ExclusionConstraintElem @@ -3710,7 +3710,7 @@ ConstraintElem: $$ = (Node *)n; } | EXCLUDE access_method_clause '(' ExclusionConstraintList ')' - opt_c_include opt_definition OptConsTableSpace ExclusionWhereClause + opt_c_include opt_definition OptConsTableSpace OptWhereClause ConstraintAttributeSpec { Constraint *n = makeNode(Constraint); @@ -3812,7 +3812,7 @@ ExclusionConstraintElem: index_elem WITH any_operator } ; -ExclusionWhereClause: +OptWhereClause: WHERE '(' a_expr ')' { $$ = $3; } | /*EMPTY*/ { $$ = NULL; } ; -- 2.11.0
