* Clean up some confusion about where and how to set whereToSendOutput.Tom Lane2001-09-08
| | | | | | | | We will no longer try to send elog messages to the client before we have initialized backend libpq (oops); however, reporting bogus commandline switches via elog does work now (not irrelevant, because of PGOPTIONS). Fix problem with inappropriate sending of checkpoint-process messages to stderr.
* Fix handling of pg_type.typdefault per bug report from Dave Blasby.Tom Lane2001-09-06
| | | | | | If there's anyone out there who's actually using datatype-defined default values, this will be an incompatible change in behavior ... but the old behavior was so broken that I doubt anyone was using it.
* For some reason, CREATE TYPE has only accepted alignment specificationsTom Lane2001-08-03
| | | | | of 'int4' and 'double'. Add 'char' and 'int2' to allow user-defined types to access the full set of supported alignments.

* Allow a non-superuser database owner to vacuum all tables in hisTom Lane2001-06-13
| | | | | | | database, including system catalogs (but not the shared catalogs, since they don't really belong to his database). This is per recent mailing list discussion. Clean up some other code that also checks for database ownerness by introducing a test function is_dbadmin().

* Rearrange order of operations in heap_create_with_catalog so that ifTom Lane2001-02-12
| | | | | | | | | two transactions create the same table name concurrently, the one that fails will complain about unique index pg_class_relname_index, rather than about pg_type_typname_index which'll confuse most people. Free side benefit: pg_class.reltype is correctly linked to the pg_type entry now. It's been zero in all but the preloaded pg_class entries since who knows when.

| | | | | values, whether the local char type is signed or not. This is necessary for portability. Per discussion on pghackers around 9/16/00.
* Revise handling of oldstyle/newstyle functions per recent discussionsTom Lane2000-11-20
| | | | | | | | | in pghackers list. Support for oldstyle internal functions is gone (no longer needed, since conversion is complete) and pg_language entry 'internal' now implies newstyle call convention. pg_language entry 'newC' is gone; both old and newstyle dynamically loaded C functions are now called language 'C'. A newstyle function must be identified by an associated info routine. See src/backend/utils/fmgr/README.
* Change SearchSysCache coding conventions so that a reference count isTom Lane2000-11-16
| | | | | | | maintained for each cache entry. A cache entry will not be freed until the matching ReleaseSysCache call has been executed. This eliminates worries about cache entries getting dropped while still in use. See my posting to pg-hackers of even date for more info.
* Arrange that no database accesses are attempted during parser() --- thisTom Lane2000-10-07
| | | | | | | | | | | | | | | 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.
* Arrays are toastable. (At least if you initdb, which I didn't force.)Tom Lane2000-07-22
| | | | | | | Remove a bunch of crufty code for large-object-based arrays, which is superseded by TOAST and likely hasn't worked in a long time anyway. Clean up array code a little, and in particular eliminate its habit of scribbling on the input array (ie, modifying the input tuple :-().
* Revise aggregate functions per earlier discussions in pghackers.Tom Lane2000-07-17
| | | | | | | | | | | There's now only one transition value and transition function. NULL handling in aggregates is a lot cleaner. Also, use Numeric accumulators instead of integer accumulators for sum/avg on integer datatypes --- this avoids overflow at the cost of being a little slower. Implement VARIANCE() and STDDEV() aggregates in the standard backend. Also, enable new LIKE selectivity estimators by default. Unrelated change, but as long as I had to force initdb anyway...

* First round of changes for new fmgr interface. fmgr itself and theTom Lane2000-05-28
| | | | | | | key call sites are changed, but most called functions are still oldstyle. An exception is that the PL managers are updated (so, for example, NULL handling now behaves as expected in plperl and plpgsql functions). NOTE initdb is forced due to added column in pg_proc.
* This is the second time I've answered this exact same problem in twoBruce Momjian2000-05-12
| | | | | | | | | | | | | | | | | | | | | days. It seems to be a FAQ, and I think I know why. When creating a 'c' language function, CREATE FUNCTION is fed the shared object filename, and seems to succeed. Only when trying to use the function is an error thrown, by which time the coder thinks something's wrong with executing the code, not with loading it. I think I once saw it proposed to load shared objects at function creation time, but that idea was shot down on the grounds of resident memory bloat, ISTR. Here's a patch for a compromise: all it does is stat() the file, just like the loader code does, so that the errors caused by non existent files, and no directory 'x' permissions (the most common ones, it seems), get caught while the developer is still thinking about code loading. It doesn't catch all errors (like the code not being readable by the postgres user) but seems to catch the most common, without actually opening the file. What do you think? Ross

* Add transcendental math functions (sine, cosine, etc)Thomas G. Lockhart2000-04-07
| | | | | | | | | | | | | | | | Add a random number generator and seed setter (random(), SET SEED) Fix up the interval*float8 math to carry partial months into the time field. Add float8*interval so we have symmetry in the available math. Fix the parser and define.c to accept SQL92 types as field arguments. Fix the parser to accept SQL92 types for CREATE TYPE, etc. This is necessary to allow... Bit/varbit support in contrib/bit cleaned up to compile and load cleanly. Still needs some work before final release. Implement the "SOME" keyword as a synonym for "ANY" per SQL92. Implement ascii(text), ichar(int4), repeat(text,int4) to help support the ODBC driver. Enable the TRUNCATE() function mapping in the ODBC driver.

* Allow CREATE FUNCTION's WITH clause to be used for all language types,Tom Lane1999-10-02
| | | | | | | not just C, so that ISCACHABLE attribute can be specified for user-defined functions. Get rid of ParamString node type, which wasn't actually being generated by gram.y anymore, even though define.c thought that was what it was getting. Clean up minor bug in dfmgr.c (premature heap_close).
* I have been working with user defined types and user defined cBruce Momjian1999-09-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | functions. One problem that I have encountered with the function manager is that it does not allow the user to define type conversion functions that convert between user types. For instance if mytype1, mytype2, and mytype3 are three Postgresql user types, and if I wish to define Postgresql conversion functions like I run into problems, because the Postgresql dynamic loader would look for a single link symbol, mytype3, for both pieces of object code. If I just change the name of one of the Postgresql functions (to make the symbols distinct), the automatic type conversion that Postgresql uses, for example, when matching operators to arguments no longer finds the type conversion function. The solution that I propose, and have implemented in the attatched patch extends the CREATE FUNCTION syntax as follows. In the first case above I use the link symbol mytype2_to_mytype3 for the link object that implements the first conversion function, and define the Postgresql operator with the following syntax The patch includes changes to the parser to include the altered syntax, changes to the ProcedureStmt node in nodes/parsenodes.h, changes to commands/define.c to handle the extra information in the AS clause, and changes to utils/fmgr/dfmgr.c that alter the way that the dynamic loader figures out what link symbol to use. I store the string for the link symbol in the prosrc text attribute of the pg_proc table which is currently unused in rows that reference dynamically loaded functions. Bernie Frankpitt

* From: Jan Wieck <jwieck@debis.com>Marc G. Fournier1998-02-25
| | | | | | | | | | seems that my last post didn't make it through. That's good since the diff itself didn't covered the renaming of pg_user.h to pg_shadow.h and it's new content. Here it's again. The complete regression test passwd with only some float diffs. createuser and destroyuser work. pg_shadow cannot be read by ordinary user.
* From: Jan Wieck <jwieck@debis.com>Marc G. Fournier1998-02-13
| | | | | | | | | Someone changed the parser to build a TypeName node on CREATE FUNCTION in any case. As a side effect, ALL! functions created got the proretset attribute to true. Thus for a SELECT the parser wrapped an Iter node around the Expr and since singleton functions set isDone the Iter returns no tuple up.
