PostgreSQL Database Management System
=====================================

This directory contains the source code distribution of the PostgreSQL
database management system.

PostgreSQL is an advanced object-relational database management system
that supports an extended subset of the SQL standard, including
transactions, foreign keys, subqueries, triggers, user-defined types
and functions.  This distribution also contains C language bindings.

PostgreSQL has many language interfaces, many of which are listed here:

	http://www.postgresql.org/download

See the file INSTALL for instructions on how to build and install
PostgreSQL.  That file also lists supported operating systems and
hardware platforms and contains information regarding any other
software packages that are required to build or run the PostgreSQL
system.  Copyright and license information can be found in the
file COPYRIGHT.  A comprehensive documentation set is included in this
distribution; it can be read as described in the installation
instructions.

The latest version of this software may be obtained at
http://www.postgresql.org/download/.  For more information look at our
web site located at http://www.postgresql.org/.

pg_trgm_pro's Issues

pg_trgm_pro for Windows?

Hi,

building pg_trgm on Windows fails:

C:\Users\abidh\source\repos\pg_trgm_pro>make USE_PGXS=1
makefile:15: C:/Program: No such file or directory
makefile:15: Files/PostgreSQL/11/lib/pgxs/src/makefiles/pgxs.mk: No such file or directory
make: *** Keine Regel, um »Files/PostgreSQL/11/lib/pgxs/src/makefiles/pgxs.mk« zu erstellen.  Schluss.

I guess currently there is no way to use the extension on Windows?

Regards

Feature request: option to include trigrams containing whitespace or special characters

I'd like to be able to include trigrams so that

similarity('foo bar', 'foo bar') > similarity('foo bar', 'bar foo')

I wish I could make it generate the o b and r f trigrams to accomplish this. Similarly I'd like

similarity('foo/bar', 'foo/bar') > similarity('foo/bar', 'foo bar')

via o/b and o b trigrams being generated.

I had implemented my own trigram index in memory for an app, but need to move the fuzzy search to the database.
In my implementation I just split the input at symbol/whitespace boundaries and yielded trigrams individually for each word,
then had a second pass over all symbols and whitespaces that only yielded trigrams that contained a symbol or didn't begin or end with whitespace.

Failed make on trgm_gin.c:42:1: error: conflicting types for 'gin_extract_value_trgm'

When I try to make it, it fails

Doesn't work on 9.5.5, second test fails

Hi! Maybe I am missing something, but on my local PostgreSQL 9.5.5
instance it doesn't work. The installation goes through as expected, but when I run the tests the 2nd test fails. "HINT: No function matches the given name and argument types. You might need to add explicit type casts." When I try to call substring_similarity manually I get the same error. Is there a way to fix it? Will attach both output files.

UPD: local issue, make install tries to install to 9.6 folder
