Thread: 7.0.2-docs: textpos -> strpos

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.

textpos() was removed from the 7.1 documentation.  position() is the SQL
function, I think strpos() is from Oracle.
