* Introduce 64-bit hash functions with a 64-bit seed.Robert Haas2017-08-31
| | | | | | | | | | | | | | | | This will be useful for hash partitioning, which needs a way to seed the hash functions to avoid problems such as a hash index on a hash partitioned table clumping all values into a small portion of the bucket space; it's also useful for anything that wants a 64-bit hash value rather than a 32-bit hash value. Just in case somebody wants a 64-bit hash value that is compatible with the existing 32-bit hash values, make the low 32-bits of the 64-bit hash value match the 32-bit hash value when the seed is 0.

* Phase 3 of pgindent updates.Tom Lane2017-06-21
| | | | | | | | | | | | | | | | | | | | | | | | | Don't move parenthesized lines to the left, even if that means they flow past the right margin. By default, BSD indent lines up statement continuation lines that are within parentheses so that they start just to the right of the preceding left parenthesis. However, traditionally, if that resulted in the continuation line extending to the right of the desired right margin, then indent would push it left just far enough to not overrun the margin, if it could do so without making the continuation line start to the left of the current statement indent. That makes for a weird mix of indentations unless one has been completely rigid about never violating the 80-column limit. This behavior has been pretty universally panned by Postgres developers. Hence, disable it with indent's new -lpl switch, so that parenthesized lines are always lined up with the preceding left paren. This patch is much less interesting than the first round of indent changes, but also bulkier, so I thought it best to separate the effects.

* Make messages mentioning type names more uniformAlvaro Herrera2017-01-18
| | | | | | | | | This avoids additional translatable strings for each distinct type, as well as making our quoting style around type names more consistent (namely, that we don't quote type names). This continues what started as f402b9950120. Discussion: https://postgr.es/m/20160401170642.GA57509@alvherre.pgsql

| | | | | Noted by Kyotaro Horiguchi, who also reviewed the previous patch, but I failed to notice his review before committing.
* Add sort support routine for the UUID data type.Robert Haas2015-11-06
| | | | | | | | | | | | | This introduces a simple encoding scheme to produce abbreviated keys: pack as many bytes of each UUID as will fit into a Datum. On little-endian machines, a byteswap is also performed; the abbreviated comparator can therefore just consist of a simple 3-way unsigned integer comparison. The purpose of this change is to speed up sorting data on a column of type UUID. Peter Geoghegan

* Downgrade implicit casts to text to be assignment-only, except for the onesTom Lane2007-06-05
| | | | | | | | | | | | | | | | | | | | | | | | | 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
* Rewrite uuid input and output routines to avoid dependency on theNeil Conway2007-01-31
| | | | | | | | | | | nonportable "hh" sprintf(3) length modifier. Instead, do the parsing and output by hand. The code to do this isn't ideal, but this is an interim measure anyway: the uuid type should probably use the in-memory struct layout specified by RFC 4122. For now, this patch should hopefully rectify the buildfarm failures for the uuid test. Along the way, re-add pg_cast entries for uuid <-> varchar, which I mistakenly removed earlier, and bump the catversion.
* Rename the uuid_t type to pg_uuid_t, to avoid a conflict with anyNeil Conway2007-01-28
| | | | | definitions of uuid_t that may be provided by the system headers. This should hopefully fix the Win32 build problems reported by Magnus.
* Add a new builtin type, "uuid". This implements a UUID type, similar toNeil Conway2007-01-28
that defined in RFC 4122. This patch includes the basic implementation, plus regression tests. Documentation and perhaps some additional functionality will come later. Catversion bumped. Patch from Gevik Babakhani; review from Peter, Tom, and myself.
