Saluton,
in the 7.0.2-docs I find the function textpos:
,----
| Table 5-5. String Functions
| ...
| textpos(text,text) text locate specified substring
| position('high','ig')
`----
However, in psql it seems one has to use strpos:
,----
| litdb=> select textpos('a b', ' ');
| ERROR: Function 'textpos(unknown, unknown)' does not exist
| Unable to identify a function that satisfies the given argument types
| You may need to add explicit typecasts
| litdb=> select strpos('a b', ' ');
| strpos
| --------
| 2
| (1 row)
|
| litdb=> select version();
| version
| --------------------------------------------------------------------
| PostgreSQL 7.0.2 on i586-pc-linux-gnulibc1, compiled by gcc 2.95.1
| (1 row)
`----
textpos does not seem to exist:
,----
| litdb=> \df .*pos
| List of functions
| Result | Function | Arguments
| --------+-----------------+------------------------
| int4 | position | text text
| float8 | positionjoinsel | oid oid int2 oid int2
| float8 | positionsel | oid oid int2 - int4
| int4 | strpos | text text
| (4 rows)
`----
Maybe this should be fixed in the docs.
Albert.
