Tom Lane	73e7025bd8	Extend format() to handle field width and left/right alignment. ... This change adds some more standard sprintf() functionality to format(). Pavel Stehule, reviewed by Dean Rasheed and Kyotaro Horiguchi	13 years ago
Tom Lane	760f3c043a	Fix concat() and format() to handle VARIADIC-labeled arguments correctly. ... Previously, the VARIADIC labeling was effectively ignored, but now these functions act as though the array elements had all been given as separate arguments. Pavel Stehule	13 years ago
Robert Haas	95dacf8593	Put back accidentally-deleted quote_literal() regression tests.	15 years ago
Robert Haas	7504870778	Add new SQL function, format(text). ... Currently, three conversion format specifiers are supported: %s for a string, %L for an SQL literal, and %I for an SQL identifier. The latter two are deliberately designed not to overlap with what sprintf() already supports, in case we want to add more of sprintf()'s functionality here later. Patch by Pavel Stehule, heavily revised by me. Reviewed by Jeff Janes and, in earlier versions, by Itagaki Takahiro and Tom Lane.	15 years ago
Robert Haas	4343c0e546	Expose quote_literal_cstr() from core. ... This eliminates the need for inefficient implementions of this functionality in both contrib/dblink and contrib/tablefunc, so remove them. The upcoming patch implementing an in-core format() function will also require this functionality. In passing, add some regression tests.	15 years ago
Itagaki Takahiro	49b27ab551	Add string functions: concat(), concat_ws(), left(), right(), and reverse(). ... Pavel Stehule, reviewed by me.	16 years ago
Tom Lane	2d4db3675f	Fix up text concatenation so that it accepts all the reasonable cases that ... were accepted by prior Postgres releases. This takes care of the loose end left by the preceding patch to downgrade implicit casts-to-text. To avoid breaking desirable behavior for array concatenation, introduce a new polymorphic pseudo-type "anynonarray" --- the added concatenation operators are actually text || anynonarray and anynonarray || text.	19 years ago
Thomas G. Lockhart	61ef6a1a3f	Clean up syntax to use SQL92-ish type coersion ... rather than the Postgres "::" notation. All of these tests have been completely inspected and give correct results.	26 years ago
Thomas G. Lockhart	1d7b6f14e2	Adjust tests to reflect removal of time travel. ... Add tests for strings and varchar.	29 years ago
Marc G. Fournier	04688df668	Again, add more tests	29 years ago
