Re: [PATCH][DOC][MINOR] Fix incorrect lexeme limit in textsearch docs

Hello,

A minor doc patch for this page
https://www.postgresql.org/docs/current/textsearch-limitations.html

and this line

- The number of lexemes must be less than 2^64

Docs wrongly claim "lexemes must be < 2^64" but the actual constraint is
1 MB total storage (MAXSTRPOS), and no 2^64 check exists in the code.

From src/include/tsearch/ts_type.h:

    #define MAXSTRPOS ( (1<<20) - 1)   // 1,048,575 bytes

    typedef struct {
        int32  size;     // number of lexemes
        ...
    } TSVectorData;

 The attached patch:

- Removes the incorrect 2^64 claim
- Clarifies this means "distinct lexemes in a single tsvector value"

Thanks,
Dharin
