Arrange that no database accesses are attempted during parser() --- this took some rejiggering of typename and ACL parsing, as well as moving parse_analyze call out of parser(). Restructure postgres.c processing so that parse analysis and rewrite are skipped when in abort-transaction state. Only COMMIT and ABORT statements will be processed beyond the raw parser() phase. This addresses problem of parser failing with database access errors while in aborted state (see pghackers discussions around 7/28/00). Also fix some bugs with COMMIT/ABORT statements appearing in the middle of a single query input string. Function, operator, and aggregate arguments/results can now use full TypeName production, in particular foo[] for array types. DROP OPERATOR and COMMENT ON OPERATOR were broken for unary operators. Allow CREATE AGGREGATE to accept unquoted numeric constants for initcond. 2000-10-07 02:58:23 +02:00			`extern List parse_analyze(Node parseTree, ParseState *parentParseState);`
First phase of SCHEMA changes, concentrating on fixing the grammar and the parsetree representation. As yet we don't do anything with schema names, just drop 'em on the floor; but you can enter schema-compatible command syntax, and there's even a primitive CREATE SCHEMA command. No doc updates yet, except to note that you can now extract a field from a function-returning-row's result with (foo(...)).fieldname. 2002-03-21 17:02:16 +01:00			`extern List analyzeCreateSchemaStmt(CreateSchemaStmt stmt);`

Clean up handling of FOR UPDATE inside views and subselects ... make it work where we can (given that the executor only handles it at top level) and generate an error where we can't. Note that while the parser has been allowing views to say SELECT FOR UPDATE for a few weeks now, that hasn't actually worked until just now. 2000-12-07 00:55:19 +01:00			`extern void CheckSelectForUpdate(Query *qry);`

Here is my much-promised patch to let people add UNIQUE constraints after table creation time. Big deal you say - but this patch is the basis of the next thing which is adding PRIMARY KEYs after table creation time. (Which is currently impossible without twiddling catalogs) Rundown ------- * I have made the makeObjectName function of analyze.c non-static, and exported it in analyze.h * I have included analyze.h and defrem.h into command.c, to support makingObjectNames and creating indices * I removed the 'case CONSTR_PRIMARY' clause so that it properly fails and says you can't add primary keys, rather than just doing nothing and reporting nothing!!! * I have modified the docs. Algorithm --------- * If name specified is null, search for a new valid constraint name. I'm not sure if I should "lock" my generated name somehow tho - should I open the relation before doing this step? * Open relation in access exclusive mode * Check that the constraint does not already exist * Define the new index * Warn if they're doubling up on an existing index Christopher Kings-Lynne 2001-09-07 23:57:53 +02:00			`/* This was exported to allow ADD CONSTRAINT to make use of it */`

Another pgindent run. Fixes enum indenting, and improves #endif spacing. Also adds space for one-line comments. 2001-10-28 07:26:15 +01:00
New pgindent run with fixes suggested by Tom. Patch manually reviewed, initdb/regression tests pass. 2001-11-05 18:46:40 +01:00			`#endif /* ANALYZE_H */`
