Re: Commands history with psql in a Windows command line shell - Mailing list pgsql-general

What happens if you use the SQL Shell from the program menu on the Start Menu?:

Thank you for your answer.

1.
Like I wrote in my first post, the command I use to launch "psql" is:
cmd.exe> psql -p <tcp_port> -U <username> <database_name>
So, I do not specify the "--no-readline" option.

2.
cmd.exe psql <database_name># \s
history is not supported by this installation

Powershell psql <database_name># \s
history is not supported by this installation

To install PostgreSQL, I used the "postgresql-9.5.2-1-windows-x64.exe" installer the 2016/04/21.
So I don't remember much about what I did that day.

3.
When I do:
psql <database_name># \set
HISTFILE does not appear in the result.
So, I guess it is not set.

The following may be pertinent.

If -n / --no-readline was specified, then command history is not used.

What happens if you issue the \s command in psql? Is history supported?

What is the value for HISTFILE?

Otherwise we have absolutely no idea what the problem might be.

"Windows (8.1)" refers to the O/S version.

Knowing the PostgreSQL version probably won't make a difference though knowing how it was installed might (though not for me personally).

cmd.exe> psql --version
psql (PostgreSQL) 9.5.2

Like I wrote, the Windows OS is 8.1 Pro.

Hello,

I am using "psql" in "cmd.exe" in Windows (8.1).

Below is the command I use to connect to a database with "psql":
cmd.exe> psql -p <tcp_port> -U <username> <database_name>

My problem is the following.
Suppose I enter one command:
<database_name># SELECT * FROM <a_table_1>;
and then another one:
<database_name># SELECT * FROM <a_table_2>;
The commands history "is not working": meaning I cannot retrieve these last two commands I entered by hitting the top arrow key.
Instead, I have to type them again.

To try to solve the problem, I entered the command:
<database_name># \set HISTSIZE 100
but it didn't change anything.

Yesterday, I don't remember what I did, but I could access the commands history using Powershell, maybe the command "\set HISTSIZE 100" and maybe a "psqlrc" file.
But whatever I've been trying to do since, I can't make it work again.

Can you please advise me what to do to make this work?

Best regards.
