Tom Lane	31edbadf4a	Downgrade implicit casts to text to be assignment-only, except for the ones ... from the other string-category types; this eliminates a lot of surprising interpretations that the parser could formerly make when there was no directly applicable operator. Create a general mechanism that supports casts to and from the standard string types (text,varchar,bpchar) for *every* datatype, by invoking the datatype's I/O functions. These new casts are assignment-only in the to-string direction, explicit-only in the other, and therefore should create no surprising behavior. Remove a bunch of thereby-obsoleted datatype-specific casting functions. The "general mechanism" is a new expression node type CoerceViaIO that can actually convert between *any* two datatypes if their external text representations are compatible. This is more general than needed for the immediate feature, but might be useful in plpgsql or other places in future. This commit does nothing about the issue that applying the concatenation operator || to non-text types will now fail, often with strange error messages due to misinterpreting the operator as array concatenation. Since it often (not always) worked before, we should either make it succeed or at least give a more user-friendly error; but details are still under debate. Peter Eisentraut and Tom Lane	19 years ago
Neil Conway	f086be3d39	Allow leading and trailing whitespace in the input to the boolean ... type. Also, add explicit casts between boolean and text/varchar. Both of these changes are for conformance with SQL:2003. Update the regression tests, bump the catversion.	19 years ago

Bruce Momjian	8096fe45ce	The added aggregates are: ... (1) boolean-and and boolean-or aggregates named bool_and and bool_or. they (SHOULD;-) correspond to standard sql every and some/any aggregates. they do not have the right name as there is a problem with the standard and the parser for some/any. Tom also think that the standard name is misleading because NULL are ignored. Also add 'every' aggregate. (2) bitwise integer aggregates named bit_and and bit_or for int2, int4, int8 and bit types. They are not standard, but I find them useful. I needed them once. The patches adds: - 2 new very short strict functions for boolean aggregates in src/backed/utils/adt/bool.c, src/include/utils/builtins.h and src/include/catalog/pg_proc.h - the new aggregates declared in src/include/catalog/pg_proc.h and src/include/catalog/pg_aggregate.h - some documentation and validation about these new aggregates.

Tom Lane	0bd61548ab	Solve the 'Turkish problem' with undesirable locale behavior for case ... conversion of basic ASCII letters. Remove all uses of strcasecmp and strncasecmp in favor of new functions pg_strcasecmp and pg_strncasecmp; remove most but not all direct uses of toupper and tolower in favor of pg_toupper and pg_tolower. These functions use the same notions of case folding already developed for identifier case conversion. I left the straight locale-based folding in place for situations where we are just manipulating user data and not trying to match it to built-in strings --- for example, the SQL upper() function is still locale dependent. Perhaps this will prove not to be what's wanted, but at the moment we can initdb and pass regression tests in Turkish locale.	22 years ago

Tom Lane	30f609484d	Add binary I/O routines for a bunch more datatypes. Still a few to go, ... but that was enough tedium for one day. Along the way, move the few support routines for types xid and cid into a more logical place.	23 years ago

Tom Lane	48165ec226	Latest round of fmgr updates. All functions with bool,char, or int2 ... inputs have been converted to newstyle. This should go a long way towards fixing our portability problems with platforms where char and short parameters are passed differently from int-width parameters. Still more to do for the Alpha port however.	26 years ago

Thomas G. Lockhart	c934ee7859	Change phrasing of input error message. ... Add istrue() and isfalse() routines to implement SQL3 IS TRUE and IS FALSE.	29 years ago
Thomas G. Lockhart	cc1b420cfd	Add routines istrue() and isfalse() to directly evaluate boolean type.	29 years ago
Thomas G. Lockhart	3eb1bc67b1	Check explicitly for valid input strings for both TRUE and FALSE. ... Allow true/false, yes/no, 1/0. Throw elog warning if anything else. Allow shorter strings, so "t", "tr", "tru" and "true" match "true". Old behavior accepted anything starting with "t" as TRUE, everything else as FALSE.	29 years ago
Thomas G. Lockhart	962c8bd66d	Accept additional values for TRUE: y, Y, 1. ... Leave all other input values to return FALSE. In next version, do more checking for valid inputs for both TRUE and FALSE.	29 years ago
Thomas G. Lockhart	a21c3e353a	Allow 't', 'T', and even/odd ASCII characters to denote true/false ... rather than just 't' and 'T'. This allows yes/no and 1/0 to be interpreted as one might expect. Clean up function declarations to use bool as the type for arguments and return values.	29 years ago
