Tom Lane	03b0a589d1	Consider interpreting a function call as a trivial (binary-compatible) ... type coercion after failing to find an exact match in pg_proc, but before considering interpretations that involve a function call with one or more argument type coercions. This avoids surprises wherein what looks like a type coercion is interpreted as coercing to some third type and then to the destination type, as in Dave Blasby's bug report of 3-Oct-01. See subsequent discussion in pghackers.	24 years ago
Bruce Momjian	5ec8474323	New comment. This func/column things has always confused me. ... /* * parse function * This code is confusing because the database can accept * relation.column, column.function, or relation.column.function. * In these cases, funcname is the last parameter, and fargs are * the rest. * * It can also be called as func(col) or func(col,col). * In this case, Funcname is the part before parens, and fargs * are the part in parens. * */ Node * ParseFuncOrColumn(ParseState *pstate, char *funcname, List *fargs, bool agg_star, bool agg_distinct, int precedence)	25 years ago

Bruce Momjian	9e1552607a	pgindent run. Make it all clean.	25 years ago
Bruce Momjian	623bf843d2	Change Copyright from PostgreSQL, Inc to PostgreSQL Global Development Group.	25 years ago
Tom Lane	ed5003c584	First cut at full support for OUTER JOINs. There are still a few loose ... ends to clean up (see my message of same date to pghackers), but mostly it works. INITDB REQUIRED!	25 years ago
Tom Lane	4b8f1bcb9c	Make functional indexes accept binary-compatible functions, for example ... CREATE INDEX fooi ON foo (lower(f1)) where f1 is varchar rather than text.	25 years ago
Tom Lane	62e29fe2e7	Remove 'func_tlist' from Func expression nodes, likewise 'param_tlist' ... from Param nodes, per discussion a few days ago on pghackers. Add new expression node type FieldSelect that implements the functionality where it's actually needed. Clean up some other unused fields in Func nodes as well. NOTE: initdb forced due to change in stored expression trees for rules.	25 years ago
Bruce Momjian	52f77df613	Ye-old pgindent run. Same 4-space tabs.	26 years ago
Tom Lane	d14c8aab99	Turns out that Mazurkiewicz's gripe about 'function inheritance' is ... actually a type-coercion problem. If you have a function defined on class A, and class B inherits from A, then the function ought to work on class B as well --- but coerce_type didn't know that. Now it does.	26 years ago
Bruce Momjian	5c25d60244	Add: ... * Portions Copyright (c) 1996-2000, PostgreSQL, Inc to all files copyright Regents of Berkeley. Man, that's a lot of files.	26 years ago
Bruce Momjian	8a093d0ae3	Make number of args to a function configurable.	26 years ago
Tom Lane	18c3000286	Teach grammar and parser about aggregate(DISTINCT ...). No implementation ... yet, but at least we can give a better error message: regression=> select count(distinct f1) from int4_tbl; ERROR: aggregate(DISTINCT ...) is not implemented yet instead of 'parser: parse error at or near distinct'.	26 years ago
Tom Lane	db436adf76	Major revision of sort-node handling: push knowledge of query ... sort order down into planner, instead of handling it only at the very top level of the planner. This fixes many things. An explicit sort is now avoided if there is a cheaper alternative (typically an indexscan) not only for ORDER BY, but also for the internal sort of GROUP BY. It works even when there is no other reason (such as a WHERE condition) to consider the indexscan. It works for indexes on functions. It works for indexes on functions, backwards. It's just so cool... CAUTION: I have changed the representation of SortClause nodes, therefore THIS UPDATE BREAKS STORED RULES. You will need to initdb.	26 years ago
Bruce Momjian	a9591ce66a	Change #include's to use <> and "" as appropriate.	27 years ago
Bruce Momjian	4b2c2850bf	Clean up #include in /include directory. Add scripts for checking includes.	27 years ago
Tom Lane	5f74d499bf	Defend against function calls with more than 8 arguments (code ... used to overrun its fixed-size arrays before detecting error; not cool). Also, replace uses of magic constant '8' with 'MAXFARGS'.	27 years ago
Bruce Momjian	07842084fe	pgindent run over code.	27 years ago

Bruce Momjian	a32450a585	pgindent run before 6.3 release, with Thomas' requested changes.	28 years ago
Marc G. Fournier	7b6cbd53f7	func_error() changed so that if caller is passed with NULL value, its ... output at least doesn't appear that its missing something. wasn't particularly confident with removing 'caller' altogether :(	28 years ago
Marc G. Fournier	48ad446c04	Fix up this so that it also doesn't use a caller variable...	28 years ago
