Simon Paredes 89d699c2e8 wrap errors instead of just formatting them 2023-12-01 18:23:23 -06:00
Sam Whited 94e56e61ba Fix usage of logger in stdlib docs 
The documentation previously showed the old way of logging and not the
newer tracer adapter. This patch updates the example to build correctly
with pgx/v5.

Jack Christensen cf6ef75f91 stdlib: Use Ping instead of CheckConn in ResetSession 
CheckConn is deprecated. It doesn't detect all network outages. It
causes a 1ms delay while it tries to read the connection. Ping incurs a
round trip but that means it is a much stronger guarantee that the
connection is usable. In addition, if the application and the database
are on the same network it will actually be faster as round trip times
are typically a few hundred microseconds.

Jack Christensen 7a2b93323c Prevent prematurely closing statements in database/sql 
This error was introduced by 0f0d236599.
If the same statement was prepared multiple times then whenever Close
was called on one of the statements the underlying prepared statement
would be closed even if other statements were still using it.

Jack Christensen 0f0d236599 database/sql prepared statement names are deterministically generated 
stdlib now uses the functionality introduced in
bbe2653bc5 for prepared statements. This
means that the prepared statement name is stable for a given query even
across connections and program executions.

It also makes tracing easier.

Andrew Kimball 3ab8941921 stdlib: Do not reuse ConnConfig strings 
Previously, stdlib.RegisterConnConfig would sometimes reuse the same connection
string for different ConnConfig options (specifically, it happened when a connection
was open and then closed, and then a new, different connection was opened). This
behavior interferes with callers that expect that two connections with the same data
source name are connecting to the same backend database in the same way.

This fix updates stdlib.RegisterConnConfig to use an incrementing sequence
counter to uniquify all returned connection strings.

Fixes #947

Jack Christensen c44cda4bb4 Clean up old Go 1.10 build tags 
pgx requires Go modules which requires at least Go 1.11 so there is no
